Metalcasting is one of the oldest manufacturing processes, dating back over five millennia.  However, recent advances continue to expand the horizons of metalcasting: new alloys and new casting techniques are leading to enhanced properties, process modeling and simulation tools are enabling better casting designs, the increasing use of metal-matrix composites is opening new frontiers in casting performance, and additive manufacturing techniques such as 3D printing of pattern materials are reducing lead times for prototype castings.  This session will cover the latest developments in ferrous and non-ferrous metalcasting technologies for the mobility industry.

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.

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.
