摘要：

A few performance criteria indicative of 'good behavior' were used to compare the results of studies on the cyclic behavior of NiTi. Plots were made that displayed the cyclic strain behavior. Strain amnesia and strain hardening were measured from the collected data. It was found that strain amnesia occurs when the material does not fully recover back to its original shape, while strain hardening is evident when the maximum strain decreases over the number of cycles for the same applied stress.
