One of the effective methods for weight reduction of valve systems in an engine is the application of titanium to the valve material. However, titanium exhaust valves that require high temperature resistance are basically expensive because they contain a lot of rare metals. Therefore, their application to a mass produced product has been very much limited. In this study, it was challenged to develop an alloy that contains only minimum required amount of rare metal elements which has a large impact to the cost, aiming at broadening the application of titanium exhaust valves. Generally speaking, heat-resisting titanium alloy has a high deformation resistance because of its superior strength at high temperature. Accordingly, its formability at high temperature is low and cracks and other defects may easily occur. In addition, when a titanium alloy is exposed with a high temperature atmosphere for a long time, oxidized scales that easily exfoliate are formed on its surface.

Motorcycles are one of the major modes of transportation globally, and further expansion of motorcycle demand and usage is expected to continue because of population growth and individual income increase, in particular in emerging countries. At the same time, approach to critical environmental issues, such as escalation of air pollution, becomes more important challenge and this trend accelerates tightening of motorcycle emission regulation globally. In accordance with this, responding to social needs and minimizing the impact on air pollution while enhancing features of motorcycles, such as drive performance, convenience, and price attractiveness are our mission as a manufacture. Platinum group metals (PGMs) such as platinum, palladium and rhodium are commonly used for automotive and motorcycle catalysts. One of catalyst researchers’ dream is ultimately to develop catalyst without using such PGMs that are precious and costly resources.

Advanced High Strength Steels (AHSS) are now commonly used in automotive body structural applications. The high strength of this grade classification is attractive to help reduce mass in the automotive body through reduction in thickness. Strength also supports improvements in safety requirements so that mass increases are minimized. In some specific grades of AHSS, energy absorption is possible in addition to the high strength. This course will review the definition and properties of AHSS and cover several common applications in automotive body structures.

The emission regulations for mobile on- and off-road applications are becoming stricter in Euro 6/Stage 5 and beyond levels and require the use of SCR for NOx and diesel particulate filter (DPF) for PM removal. The presence of wall-flow filter with active regeneration creates a risk of thermal deactivation of SCR catalyst in the aftertreatment system (ATS). The thermal and chemical durability of Cu- and Fe-SCR catalysts were screened and developed to stand these conditions. The performance of catalysts were investigated with laboratory simulations and engine-bench equipments. New Cu-SCR catalysts have a very high low-temperature SCR activity and a low dependency on NO2 promotion. Developed Fe-SCR catalysts showed also an improved low temperature activity and durability but were more dependant on NO2 concentration too. Low N2O formation with Cu-SCR catalyst is a key factor to minimize green house gas emissions.

Aluminum skin milling is a very challenging process due to the high quality requirements needed in the aeronautic and aerospace industries. Nowadays, on these markets, there are just two technological approaches able to face the manufacturing of this sort of wide thin blanks: chemical and mechanical milling by means of highly complex machines. Both solutions lead to a high investment requirement that affect directly on the application profitability on these industrial sectors. This paper presents a flexible machining system that allows milling skin shaped parts within required tolerances by means of an innovative universal holding fixture combined with an adaptive toolpath development. This flexible holding fixture can be adapted to the required shape and can hold uniformly the whole sheet surface. Besides, the solution includes an implementation that can adapt the machining toolpath by means of the skin thickness online measurement.

This paper presents an approach to how existing production systems can benefit from Industry 4.0 driven concepts. This attempt is based on a communication gateway and a cloud-based system, that hosts all algorithms and models to calculate a prediction of the tool wear. Refill Friction Stir Spot Welding is a sub-section of friction welding, where a rotating tool that consists out of three parts is used to heat up material to a dough-like state. Since Refill Friction Stir Spot Welding produces a selective dot-shaped connection of overlapping materials, the production requirements are similar to riveting or resistance spot welding. In contrast to other bonding techniques, Refill Friction Stir Spot Welding can be integrated within the production process without major interferences or changes.

Despite the increasing use of carbon fibre reinforced plastic (CFRP) composites, titanium and aluminium alloys still constitute a significant proportion of modern civil aircraft structures, which are primarily assembled via mechanical joining techniques. Drilling of fastening holes is therefore a critical operation, which has to meet stringent geometric tolerance and integrity criteria. The paper details the development of a three-dimensional (3D) finite element (FE) model for drilling aerospace grade aluminium (AA7010-T7451 and AA2024-T351) and titanium (Ti-6Al-4V) alloys. The FE simulation employed a Coupled Eulerian Lagrangian (CEL) technique. The cutting tool was modelled according to a Lagrangian formulation in which the mesh follows the material displacement while the workpiece was represented by a non-translating and material deformation independent Eulerian mesh.

Aluminum metal matrix composite brake rotors with a selective ceramic function reinforcement gradient (FRG) have been developed for automotive applications. This paper will highlight the design, manufacturing, and testing of the rotors. Weight saving of an aluminum composite rotor in comparison to an industry standard cast iron rotor is 50-60%. With this material change comes design considerations to manage rotor temperature, rotor surface integrity, and friction. Manufacturing methods to meet these design constraints were needed to develop a viable high performance aluminum composite rotor. High pressure squeeze casting with soluble coring techniques were developed to incorporate the selective FRG MMC rotors. Dynamometer testing was performed, concentrating on brake friction and temperature to evaluate the macro and micro interfaces in the rotors.

A trend in automotive parts development is the pursuit of long life, high quality and reliability. The increase in service life of automotive wheel bearings, by improving the rolling contact fatigue (RCF) life of bearing steels, was investigated. Conventional studies of bearing steels and heat treatments have dealt with quenching and tempering (Q/T) in 52100 steel. This study is a new trial to increase the strength of bearing steels by special austempering in phases after general Q/T heat treatments.

Developing a brake system with high overall customer satisfaction rating is a constant challenge for OEMs as well as their brake suppliers. Brake system performance is directly linked to the engagement between the rotor and pads. The materials for the rotors and pads play a key role in the nature of the engagement. Therefore, it is critical to have a good understanding of brake rotor materials to meet performance targets. Due to its superior thermal handling capacity, damping characteristics, wear and cost advantages, gray iron is the most widely used brake rotor material in the industry. G30 per ASTM A48 is generally specified for most brake rotors with minimum tensile strength of 200 Mpa and Brinell hardness of 187~241. G20 is also widely used for brake rotors, especially when people are looking for brake smoothness and optimal pad life. This study has found that variation in gray iron material can considerably affect brake output, wear, DTV, BTV, and noise propensity.

Abstract The lifting and excavating industry are not as advanced as automotive in the use of modern CAE tools in the early stages of design and development of heavy machinery. There is still a lack of confidence in the integrity of the results from FE simulations and optimisation and this becomes a barrier to the adoption of virtual prototyping for vehicle verification. R&D of Tata Steel has performed tests on two forklift truck overhead guards supplied by a major manufacturer. Based on the international standard for Falling Object Protective Structures (FOPS) as an initial input to the method of testing, the main aim of this study was to generate as much test data as possible to correlate the Finite Element (FE) simulations of two tests - a static and a dynamic test. The static test was developed to deform the overhead guard plastically in a slow controlled manner, so it would be easier to correlate the measured data to FE simulation.
