Fracture behavior of a shape memory alloy at high loading velocity and high temperature

摘要

The fracture behavior under high-loading velocity and at high temperature was investigated using tensile testing system for a shape memory alloy. Both SEM and X-Ray were used to examined the testing sample before and after tensile testing. It was found that the fracture behavior shows some similar tendency between at high-loading velocity and high-temperature. Based on the results, it can be confirmed that the shape memory alloy can be used to develop high performance intelligent material with high-impact resistance.
