DEFORMATION OF CuZnAl SHAPE MEMORY ALLOYS IN MARTENSITIC STATE

E.HORNBOGEN  
【摘要】:正 Plastic deformation of three CuZnAl shape memory alloys in martensitic state was investi-gated by means of optical and electron metallography,dilatometry and electric resistiviy de-termination.Two of the alloys are in martensitic state at ambient temperature,and theA_f temperature of the third one is far below the ambient temperature.The effect ofdeformation of alloys in martensitic state on the course and temperature of transformation aswell as the hysteresis of transformation cycles has been analyzed and the “effect of the firstcycle” has also been discussed.
