Semisolid metal forming by novel sloping plate process GUAN Ren-guo(管仁国), WANG Chao(王 超), SHANG Jian-hong(尚剑洪), XING Zhen-huan(邢振环) College of Materials and Metallurgy, Northeastern University, Shenyang 110004, China Received 28 July 2006; accepted 15 September 2006 Abstract: Semisolid metal forming by a novel sloping plate process was studied. A sloping plate with wavelike surface was used......

strength steel gear drum was produced by hot spline forming using resistance heating of side wall of a cup. V-shaped hot forming using sealed air was developed to produce ultra-high strength hollow axle beams used for suspensions of automobiles. A one shot hot stamping process consisting of resistance heating, forming, shearing and die quenching was applicable to comparatively small high strength......

The forward hot extrusion process is simulated with finite element method......
an 800 Ton SPF press. As superplastic forming processes are very sensitive to the forming temperature and forming pressure, special care needs to be taken in the control of temperature and gas pressure. In this experiment, forming temperature was maintained in the tool by cartridge heaters within the press platen, and the gas mass flow was controlled by pneumatic proportional valves, which were......

Numerical simulation of temperature field in plasma-arc flexible forming of laminated-composite metal sheets SONG Wen-qing(宋文庆)1, XU Wen-ji(徐文骥)1, WANG Xu-yue(王续跃)1, MENG Jian-bing(孟...; Abstract: Flexible forming of laminated-composite metal sheets (LCMS) using plasma arc is a latest technique, which produces LCMS components by thermal stress......
aforementioned have been successfully used in some cold metal forming processes. However, the extension of the fracture criteria to hot forming processes is difficult because ductile fracture is a complicated... to center of sample The damage value obtained by Oyane criterion in cold metal forming is usually a constant. However, for hot metal forming processes, the critical fracture values increase with increasing......
