Abstract
The time evolution of internal friction and shape change in different microstructural states of two Cu-Zn-Al shape memory alloys has been in vestigated. In the single-martensite phase state, the monotonic decrea se of internal friction with time is attributed to the pinning of mart ensite/martensite interfaces. When the parent phase is present, the ch ange in the internal friction is associated with the formation of stre ss-induced martensite and the subsequent pinning of the martensite/par ent and martensite/martensite interfaces.
