Abstract

The mechanical behavior of a martensitic NiTi shape memory alloy (SMA) under very high strain rate compression was obtained and compared to its low rate deformation behavior. The alloy remained martensitic during compression at a strain rate of 3000 s^-1. Stress-strain curve characteristics were insensitive to the deformation rate for changes in the strain rate as high as 10⁷. The stabilization of the martensite after deformation appeared to be independent of the strain rate.
