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 the A_f temperature of the third one is far below the ambient temperature.The effect of deformation of alloys in martensitic state on the course and temperature of transformation as well as the hysteresis of transformation cycles has been analyzed and the “effect of the first cycle” has also been discussed.
