217 Influence of shot peening to mechanical properties of TiNi shape memory alloy

Abstract

In order to make the TiNi shape memory alloy (SMA) with arbitrary shape couture, the lost wax fine casting and self-propagating high-temperature synthesis (SHS) method can be applied. However, the SMA produced by these methods donot carries out some process. Thus the shot peening process is applied to improve the mechanical properties of SMA instead of cold roll process. In this study, we investigated the effect of the shot peening process for the improvement of the properties of SMA.
