The intersection is happening. The intersection between the vehicle and the product world is finally happening. And one quick walk on this year’s CES at Las Vegas and NAIAS at Detroit will ascertain the right confluence of the same. Albeit the apparent differences in the lead-time of the development processes, there is a lot to be cross-pollinated between these two not-so-distinct ecosystems. Because fundamental core sits the end user – the human being. And prevalent school of thoughts in both the disciplines are rightfully acknowledging the human centricity needed to plan for and design “objects” and “services” as an seamless offering. Gone are the days to just push metal or cheap plastic artifacts to the consumer, as that definition of consumer itself is changing.

Event
In this talk, we will explore some conceptual use cases of Augmented Reality in manufacturing and other industrial applications, and the technology gaps that currently exist preventing them from turning into a reality. We’ll elaborate on this theme by looking at how current marketing for this technology has led to over-inflated expectations for what exists today, and the effect that is having on its perception outside of the community. To continue we will look at work being done both in industry and academia to address these technology gaps and how we are moving closer to meeting those expectations, and finally we’ll uncover the huge benefits in manufacturing operations once we are successful.

This paper presents an overview of a four-year project on integrated computational materials engineering (ICME) for third generation advanced high-strength steels (3GAHSS) development. Following a brief look at ICME as an emerging discipline within the Materials Genome Initiative, technical tasks in the ICME project will be discussed. Specific focus of the individual tasks is on multi-scale, microstructure-based material model development using state-of-the-art computational and experimental techniques, forming, assembly, design optimization, integration and technical cost modeling. The integrated approach is illustrated using a 980 grade transformation induced plasticity (TRIP) steel with a two-step quenching and partitioning (Q&P) heat treatment as an example.

This method and its special process are particularly suited for the production of Porous free combustion chamber proto type aluminium cylinder head casting. Current methods for producing porus free combustion chamber are graphite coating and CI/Cu metal chill which are moderately effective in achieving porus free combustion chamber. However, these current methods have serious drawbacks like high rejections due to blow holes/gas porosity generated from graphite coating and fine porosity due to prolonged cooling because of slow rate of cooling while peak temperature of metal chills. Using a typical aluminum alloy such as A356 or EN AC-AlSi7mg for prototype casting in regular sand casting practice, large SDAS (> 50 Чm) and medium amount of hydrogen content are possible in a prototype head.

Springback prediction is challenging for Automotive Industry due to use of High Strength Steel (HSS). Automotive OEMs are working to reduce the springback effect of sheet metal stampings caused due to elastic behavior of materials with the help of changes to manufacturing process and part geometry. Use of HSS has grown due to improved passive safety (higher strength) and reduced vehicle weight. This on the other hand tends to intensify the springback effect, as the HSS materials have a higher elastic limit. Recent development in FEA studies made it possible for the industry to rely on stamping simulation. There is always a gap between the springback predicted from stamping simulation and the actual stamped part. Currently FEA technique is not able to accurately predict this gap. The objective of this study is to minimize this gap using DFSS method for predicting the springback and optimizing the simulation parameters with the help of LS-Dyna FEM tool.

Magnesium die-cast alloys are known to have a layered microstructure composed of: (1) An outer skin layer characterized by a refined microstructure that is relatively defect-free; and (2) A “core” (interior) layer with a coarser microstructure having a higher concentration of features such as porosity and externally solidified grains (ESGs). Because of the difference in microstructural features, it has been long suggested that removal of the surface layer by machining could result in reduced mechanical properties in tested tensile samples. To examine the influence of the skin layer on the mechanical properties, a series of round tensile bars of varying diameters were die-cast in a specially-designed mold using the AM60 Mg alloy. A select number of the samples were machined to different final diameters. Subsequently, all of the samples (as-cast as well as machined) were tested in tension.

Quenching and partitioning (Q&P) is a novel heat treatment to produce third generation advanced high-strength steels (AHSS). The influence of carbon on mechanical properties of Q&P treated CMnSi-steels was studied using 0.3C 1.5Mn 1.5Si and 0.4C 1.5Mn 1.5Si compositions. Two step Q&P treatments following full austenitization were conducted using varying partitioning times and a fixed partitioning temperature of 400 °C and the results were compared with literature data for 0.2C 1.5Mn 1.5Si Q&P treated steels. The comparison shows that increasing the carbon content from 0.2 wt pct to 0.4 wt pct increases the ultimate tensile strength by 140 MPa/0.1 wt pct C up to 1610 MPa without significantly decreasing ductility. Increased alloy carbon content did not substantially increase retained austenite fractions. The best combinations of UTS and TE were obtained using short partitioning times.

Abstract Ablation casting is an emerging technology which combines traditional sand molding techniques with rapid cooling due to the use of a water soluble binder. High cooling rates and control of solidification direction allows for exceptional mechanical properties and complex shapes. Through the use of ablation, six different body node castings have been manufactured for the 2016 NSX aluminum space frame. The high mechanical properties allowed these castings to be integrated into the crash structure for energy absorption. Using the traditional casting alloy A356, target mechanical properties were 190 Mpa Yield Strength, 280 Mpa Tensile Strength and 12% min elongation. The high elongation was achieved due to the refined eutectic microstructure produced by high cooling rates. The eutectic microstructure produced by ablation was found to be Level 5 or 6 on the AFS scale. Light weighting could also be achieved when compared to traditional GDC castings.

Abstract In this research, a new wire material made using surface-reforming heat treatment was developed in order to enhance the corrosion fatigue resistance of suspension springs. The aim of surface reforming is to improve hydrogen embrittlement characteristics through grain refinement and to improve crack propagation resistance by partial softening of hardness. The grain refinement method used an α'→γ reversed transformation by rapid short-term heating in repeated induction heating and quenching (R-IHQ) to refine the crystal grain size of SAE 9254 steel spring wire to 4 μm or less. In order to simultaneously improve the fatigue crack propagation characteristics, the possibility of reducing the hardness immediately below the spring surface layer was also examined. By applying contour hardening in the second IHQ cycle, a heat affected zone (HAZ) is obtained immediately below the surface.

Abstract The uniaxial compression test was used to assess the influence of strain amount on the behavior of precipitates and texture of the Al-7%Si-1%Cu-0.5%Mg alloy, modified with micro-additions of V, Zr and Ti. As revealed through metallographic examinations, fracturing and re-orientation of the second-phase particles increased with increasing compression strain. However, the intermetallic particles experienced substantially more frequent cracking than the eutectic silicon. The crystallographic texture was measured and correlated with deformation behavior of the alloy. The weak texture of 11<211> and 111<110> components, detected after casting transformed to a mixture of 1<110>, 112<110> and 111<110> components after room-temperature compression deformation. The intensity of the texture components depended on the strain amount. It is concluded that the texture formation in the studied alloy is controlled by the precipitates formed during solidification of the alloy.

Abstract A new nitriding technology and material technology have been developed to increase the strength of microalloyed gears. The developed nitriding technology makes it possible to freely select the phase composition of the nitride compound layer by controlling the treatment atmosphere. The treatment environment is controlled to exclude sources of supply of [C], and H2 is applied as the carrier gas. This has made it possible to control the forward reaction that decomposes NH3, helping to enable the stable precipitation of γ′-phase, which offers excellent peeling resistance. A material optimized for the new nitriding technology was also developed. The new material is a low-carbon alloy steel that makes it possible to minimize the difference in hardness between the compound layer and the substrate directly below it, and is resistant to decline in internal hardness due to aging precipitation in the temperature range used in the nitriding treatment.

Abstract In this paper, the evolution equation for the active yield surface during the unloading/reloading process based on the pressure-sensitive Drucker-Prager yield function and a recently developed anisotropic hardening rule with a non-associated flow rule is first presented. A user material subroutine based on the anisotropic hardening rule and the constitutive relation was written and implemented into the commercial finite element program ABAQUS. A two-dimensional plane strain finite element analysis of a crankshaft section under fillet rolling was conducted. After the release of the roller, the magnitude of the compressive residual hoop stress for the material with consideration of pressure sensitivity typically for cast irons is smaller than that without consideration of pressure sensitivity.

Abstract In a multi-pass weld, the development of residual stress to a large extent depends on the response of the weld metal, heat affected zone and parent material to complex thermo-mechanical cycles during welding. Previous investigations on this subject mostly focused on mechanical tensioning or heat treatment to modify the residual stress distribution in and around the weld. In this research, microstructural refinement with modification of residual stress state was attempted by applying post weld cold rolling followed by laser processing. The hardening of the weld metal was evaluated after welding, post weld cold rolling and post weld cold rolling followed by laser processing. The residual stress was determined non-destructively by using neutron diffraction. Hardness results showed evidence of plastic deformation up to 4 mm below the weld surface.

Fracture split forged steel connecting rods are utilized in many new high performance automotive engines to increase durability. Higher strength levels are needed as the power density increases. Fracture splitting without plastic deformation is necessary for manufacturability. Metallurgical design is a key for achieving the required performance levels. Several medium carbon steels containing 0.07 wt pct P, 0.06 wt pct S and various amounts of Mn, Si, V, and N were produced by vacuum induction melting laboratory heats and hot working the cast ingots into plates. The plates were cooled at varying rates to simulate typical cooling methods after forging. Microstructures were generally ferrite and pearlite as evaluated by light optical and scanning electron microscopy.
