Abstract
The making process of Cu-Zn-Al shape memory alloys by powder-metallurgycal (P/M) method were studied, being expected that the functional properties would be superior to those of normal method such as melting method. The results obtained were as follows: 1) The properties of the sintered compact obtained by master-alloyed method were better than those by both elemental and pre-alloyed methods. 2) The relative density of the alloy by the master-alloyed method attained to about 98% when it was added 0.1% of A1F3 as a sintering accelerator and was sintered at 1173K. 3) The grain size of the alloy by P/M method was 20-100um, and was much finer than that by the normal method.
