主　　题：CuAlNi alloy shape memory alloy martensitic transformation 

摘      要：The effect of composition and heat treatment on the phase constituent,the size of B2-and DO_3 derived domains and martensitic thermoelastic behaviour in three CuAlNi alloys have been studied by means of metallography,TEM anti X-ray diffraction *** is shown that the structure of martensite changes from 18R_1 into 2H and the transition temperature decreases with the increase of the Al ***,the size of the B2 and DO_3 derived domains decreases with the increase of cooling rate.
