Heat Treatment of Ni-Ti Alloy for Improvement of Shape Memory Effect

Effect of cooling rate on the phase transformation behavior and mechanical properties of Ni-rich NiTi shape memory alloy

“…Cooling rate, heat treatment temperature and time all determine the forward and reverse phase transition temperatures between the martensitic phase and the austenitic phase. These processing parameters also affect the R-phase transition [8][9][10]. Inasmuch as phase * Corresponding author.…”

EIS study of porous NiTi biomedical alloy in simulated body fluid

“…Due to their unique shape memory properties, superelasticity, resistance to fatigue and corrosion, biocompatibility, and bioactivity, they have been utilized in biomedical applications as implants and prostheses [1][2][3][4][5][6].…”

Effect of Mechanical Alloying and Sintering on Ni–Ti Powders

“…[17][18][19] Although considerable achievements have been obtained on Ni-Ti Shape memory alloy (SMA) during past years, there are still controversies on how to precisely control the SMA characteristics. [20] An important issue is the choice of alternative production methods as they affect the chemical homogeneity, the porosity, and the contaminants added to the melt. It is, therefore, agreed upon that, although the conventional methods like electric arc melting, vacuum induction melting or combustion synthesis [21] are suitable for production of Ni-Ti alloys, powder metallurgy must also be considered as a beneficial way of production of the near-net-shape, fine-grain material that can be applicable to the aerospace, automotive, or biomedical industry.…”
