Internal Friction in a Shape Memory Alloy Cu-Zn-Al under Equilibrium Condition

1. Introduction CuZnAl shape memory alloys have beenextensively studied as a new type of material.Dejonghe1]et al. firstly reported theirresults on the internal friction (IF) of CuZnAlalloys in 1975. Later, some researchershave done much work on internal friction.But most of them were concerned withphase transformation internal frictionof martensite and reverse martensite andfew of them were about internal friction
