英国曼彻斯特大学和曼彻斯特大学理工学院的 G H Zahid 等研究了由粉末冶金技术制备的2124/SiC_p 铝合金复合材的超塑性。样品用温轧代替任何一种特殊的热机械工艺或热挤压工艺,使其具有超塑性试验前的细晶粒。复合材的超塑性行为是由恒定的应变速率测定的。所有的试验是在743～783K、应变速率为10~(-2)～10~(-1)s~(-1)的空气中进行。在 G H Zahid et al at the University of Manchester in the UK and the University of Manchester Institute of Technology studied the superplasticity of 2124 / SiC_p aluminum alloy composites prepared by powder metallurgy. The sample was replaced by warm rolling for any particular type of thermo-mechanical or hot-extrusion process to provide a fine grain before the superplasticity test. The superplastic behavior of the composites is determined by a constant strain rate. All experiments were performed in air at 743-783 K and strain rate of 10 -2 (s -1) -1 s -1. in
