%X Comparing with ZHMn55-3-1 alloy,stress corrosion cracking experiments on Cu-Al-Be SMAs in media of glycerol,sea water and ammonia were carried out and the tensile fractures of experimental alloys were investigated by SEM.The result was clear that Cu-Al-Be SMAs show a high resistance to stress corrosion cracking,especially in sea water. Martensities have good ability against corrosion in sea water and the twin deformation and motion of the interfaces of the martensite variants is able to relieve stress concentration and delay the extending of corrosion cracks.Both of them exert a contribution to improving the SCC character of Cu-Al-Be alloys.
