Effect of Hot-Forging on NiTi Shape Memory Alloy Fibers Reinforced Mg Alloy Composite Qi Guoa , Gang Lib , Renjian Tangc, Biao Yan d 1 School of Materials Science and Engineering, Tongji University, 200092 Shanghai, China a guo1022@hotmail.com, b ligfriday@yahoo.com, ctrj95866@sina.com, d yanbiao@vip.sina.com Keywords: NiTi shape memory alloy fiber, Mg alloy composite, hot-forging Abstract.
Introduction Mg alloy matrix composites are considered as advanced materials due to their light weight, high specific strength, high modulus, low coefficient of thermal expansion, as well as good creep resistance.
Especially, the tensile strength as high as 247MPa is much higher than that of composite fabricated with the pulsed current hot pressing process, and an elongation of 7.5% is better than that of the composite reinforced with ceramic materials.
