“…Domblesky et al [44] produced bi-metal preforms from copper, aluminium and steel pairs to determine weld characteristics such as grain structure at the interface. Behrens et al [15] investigated the performed metallographic analyses and evaluated the bond strengths for laser beam welding and friction welding of a bi-metallic C22.8 (1.0460) and 41Cr4 (1.7035) steel rod. The results do demonstrate high strength bond formation, with the component failing in the lower strength base material steel (1.0460) rather than the bond region for both forms of bonding.…”

This paper provides a review of recent developments in the manufacturing of lightweight multi-metal components, and in particular gears. The literature has shown that significant efforts have been made in manufacturing light gears and numerous technical challenges exist when designing for and manufacturing with dissimilar metals including challenges in heating technologies, mechanical performance, processing parameters, metal compatibility and the interface layer between adjacent materials, as well as difficulties in multi-metal simulations. Whilst the scope of multi-metal manufacturing is vast, the main concentration of this study is on the main stages of multi-metal gear production, and specifically on preform production, multi-metal heating, intermetallic bonding, and modelling of essential forming parameters. The effects of each of these methods as well as the numerous approaches studied in the literature are presented, with a recommendation being made as to a processing route that may lead to a robust multi-metal gear with minimal production line modifications to conventional steel gears.

“…3 shows the schematic representation of the different welding surface geometries of the 37CrS4 steel alloy, as well as the tensile specimens used to characterise the global and local bond strength. In order to determine the critical stresses that lead to failure of the joining zone, the resulting joining zones were investigated analogously to previous work of the authors [14] by uniaxial tensile tests. The determination of the bond strength of the hybrid components with different welding surface geometries was initially carried out globally, i.e.…”

“…To evaluate the influence of the conical weld surface geometries locally, flat tensile specimens were subsequently prepared and characterised from the cross-section of the semi-finished products. Therefore, six small flat tensile specimens (specimen number 1 to 6) were prepared analogously to the method described in [14] by wire erosion every 2 mm along the cross-section of the hybrid semi-finished products, as sketched in Fig. 3.…”

Bulk metal components are often used in areas which are subjected to very high loads. For most technical components, a distinction between structural and functional areas can be made. These areas usually have very different loading profiles, sometimes with contradictory requirements. Nevertheless, nowadays almost only monomaterials are used for the production of bulk metal components. With increasing requirements towards more and more efficient products with lower weight, compact design and extended functionality, these materials are reaching their material-specific limits. A significant increase of product quality and economic efficiency can be expected exclusively with locally adapted properties by combining different materials within one component. In this regard, the focus of this contribution is the production of a hybrid pinion shaft made of the material combination steel (37CrS4) and aluminium (AW6082). The tool concept for extrusion of the hybrid preform, the simulation-based design of the forming process as well as the material characterisation are presented. With the help of the FE-simulation, different serially arranged semi-finished component geometries were investigated in order to minimise the occurring tensile stresses in the component during the extrusion process to prevent failure during forming.

“…Rotary friction welding is suitable for welding different materials that cannot be joined by other welding processes [45]. For friction welding of hybrid components, various investigations have been carried out in the CRC 1153 in which the strengths of steel-steel alloy combinations have been analyzed [46], also in comparison to US laser beam welding [45]. In addition, the strengths of steel-aluminum alloy combinations at different temperatures have been investigated [47].…”
