process. A new concept of hollow billet was proposed and a method of extrusion from hollow billet was developed in order to reduce the maximum forming load. The schematic diagram of extrusion from hollow... Tech, 2004, 151(1/3): 289-293. [13] OGAWA N, SHIOMI M, OSAKADA K. Forming limit of magnesium alloy at elevated temperatures for precision forging [J]. International Journal of Machine Tools &......
die was carried out. The schematic diagram of superplastic blow forming is shown in Fig.10. This test was performed on the 1 000 kN superplastic forming machine. The SPF machine consists of a heater..., and the trials have confirmed the potential of the ZrO2-TiO2 ceramic die. Fig.10 Schematic diagram of superplastic forming Ti6Al4V deep cylinder with ceramic die: 1 Blank holder; 2 Air inlet......
forming and solid state sintering. The wick could be divided into two parts for liquid capillary pumping flow: groove sintered zone and uniform sintered zone. Both of the thermal resistance network model and the maximum heat transfer capability model of GSHP were built. Compared with the theoretical values, the heat transfer limit and thermal resistance of GSHP were measured from three aspects......
Prediction of stiffener buckling in press bend forming of integral panels YAN Yu1, WANG Hai-bo1, WAN Min2 1. College of Mechanical and Electrical Engineering, North China University of Technology... the buckling of stiffeners in the press bend forming of the integral panel, a method for solving the critical buckling load of the stiffeners in press bend forming process was proposed based on energy......
). The relationship between LDH and forming temperature are shown in Fig.3. For isothermal forming, the fracture occurs at dome center and is independent of forming temperature. But the limit dome height...
