Since the addition of Hf or Zr provides a cost-effective alternative to NiTi alloyed with Pd, Pt
and Au, due to the high cost of the latter, NiTiHf and NiTiZr alloys have recently attracted …

Shape Memory Alloys (SMAs) are unique materials able to undergo a thermomechanically
induced, reversible phase transformation. Additionally, SMA are subject to two types of …

Abstract Shape Memory Alloys (SMAs) are a unique type of metallic alloys which exhibit a
reversible, crystallographic phase transformation between austenite and martensite. SMAs …
