Isothermal Aging Kinetics in CuZnAl Shape Memory AlloyZengqi ZHAO Lab.of Physics,Baotou Research Institute of Rare Earth,Baotou,014010,ChinaFeixia CHEN Dazhi YANG Dept.of Mater.Eng.,Dalian University of Technology,Dalian,116024,ChinaEr BAO Dept.of Mater.Eng.,Yanshan University,Qinhuangdao,066004,China摘 要:<正> Isothermal aging behaviours of a CuZnAl......
of the re-aged Cu-Ni-Si alloy are discussed. The results indicate that the pre-aging process for Cu-Ni-Si alloy was responsible to the significant strengthening effect in re-aging process, and the re-aging strengthening effect with pre-aging at 450℃ for 8h was even more remarkable. Upon aging, a phenomenon of simultaneous in situ and discontinuous recrystallization was observed in the treatment......
