Paper Title:
Transformation Behavior and Mechanical Properties of an Equiatomic Ti-Ni Alloy with Surface Sulfide Layers
  Abstract

Surface sulfide layers were formed on the surface of Ti-50.0(at%)Ni alloys by isothermal annealing at 873 K for 3.6 ks under the sulfur pressure of 80 kPa, and then transformation behavior and mechanical properties were investigated by means of differential scanning calorimetery(DSC), thermal cycling tests under constant load, and tensile tests. The DSC peaks were broadened and martensitic transformation start temperature(Ms) increased from 281 K to 289 K by sulfurization. An equiatomic Ti-Ni alloy with surface sulfide layers showed good shape memory characteristics and partial superelasticity.
