Abstract

SMST-2013:The International Conference on Shape Memory and Superelastic Technologies

In recent years high temperature shape memory alloys (HTSMAs) such as NiTiPd were the subject of numerous research projects due to their near perfect pseudoelasticity and shape memory behavior at elevated temperatures for the intended use in superelastic and damping applications in aerospace and automotive industries [1]. However, the high costs for elements such as Pt and Pd and brittleness are major roadblocks. Co-based alloys such as CoNiAl and CoNiGa benefit from low costs and good ductility [1-5].
