“…Park et al have predicted metal flows and volume change during die-forging with the rigid-plastic finite element analysis and successfully designed the preform for precision forging of an asymmetric rib-web component [16]. Petrov et al have applied QFORM-3D for the numerical investigations of the metal flow of isothermal forging and determined the optimum process conditions for isothermal enclosed die forging to fabricate A92618 aluminum alloy part with irregular shape [17]. Otherwise, Zhang et al investigated the influence of forging process parameters on the distribution of flow lines in 7075 aluminum alloy disk workpiece with complex shape [18].…”

There is an increasing demand for magnesium alloy in the automobile and aerospace industries, but the large-size magnesium alloy forging is difficult to be obtained by conventionally machining with high mechanical properties. The isothermal forming was carried out to form the large-size magnesium alloy forging. The forming process of isothermal forming is studied by finite element model simulation and experiment. The microstructure and tensile properties of the magnesium alloy forging processed by isothermal forming after T5 heat treatment are analyzed. The flow lines and texture played important roles in mechanical properties of the magnesium alloy forging. The ultimate tensile strength, yield strength, and elongation of the web of the forging at room temperature after T5 heat treatment were as high as 370.6 MPa, 280.2 MPa, and 7.5 %, respectively. At 130°C, the web of the forging had the highest tensile properties, which followed the same trend as those at room temperature, with the ultimate tensile strength, yield strength, and elongation as high as 258.4 MPa, 186.1 MPa, and 42.8 %, respectively, which showed the excellent mechanical properties.

“…[1][2][3][4] Although there have been many attempts to replace conventional steel and casting materials with lightweight metals such as magnesium alloys and titanium alloys in various panels of automobiles, aluminium alloys are currently one of the best candidate materials for lightweight design in the transportation industries [5][6][7][8][9] since they show a high specific strength and a good recyclability; however, aluminium alloys have had only limited application to the suspension, steering and bumper components of automobiles, because of their high manufacturing cost and the difficulties in their heat treatment and their grain size control during warm-forging conditions. [10][11][12][13] Shan et al 14 demonstrated a forming technology related to isothermal precision forging, and Yoshimura and Tanaka 15 introduced net-shape forming with steel and aluminium alloys using enclosed die forging equipment. Forcellese and Gabrielli 16 proposed a new warmforging sequence and solution heat treatment to improve the mechanical properties of aluminium alloy AA6082.…”

This paper presents a warm-forging process for the manufacture of an aluminium alloy differential case in an automobile, which has usually been produced from ductile cast iron. In order to replace the conventional ductile cast iron with a lightweight material in the differential case, aluminium alloy 6082 is utilized in the proposed warm-forging process, which is then analysed by numerical simulations using DEFORM-3D. Experimental warm forging using aluminium alloy 6082 was conducted in a 1600 tonf press shop to evaluate the proposed design in the die and the punch as well as the forgeability of the aluminium alloy differential case. The as-forged aluminium alloy differential case not only provides a net shape but also has a crack-free volume internally, while reducing the total weight by about 40% based on the proposed design.
