Abstract: The effects of quenchant temperature on the stabilization and property of Cu Zn Al alloy were investigated by means of X ray diffraction and electrical resistivity measurement. Experimental results show that, when the quenchant temperature is higher than Af, thermoelastic martensite will be obtained; when the quenchant temperature is between Ms and M f, martensite will exhibit partial stabilization and when the quenchant temperature is lower than Mf, martensite will be stabilized. The stabilization may be in close relation with the suppression of B2-D03 transformation.
