Description
Summary:Due to their biocompatibility, superelasticity, and corrosion resistance, binary and ternary NiTi (NiTiNOL) shape memory alloys (SMAs) are at the forefront of materials research for biomedical applications. The first half of the study reviews the biocompatibility and uses of NiTi SMAs. Traditional machining techniques have difficulty dealing with binary and ternary NiTi SMAs. The second half of the research discusses the literature review of unconventional SMA machining techniques from laser beam to wire electrical discharge machining (Wire EDM). Significant output responses, such as surface roughness and material removal rate, are also investigated as a function of numerous non-traditional machining process input factors. The conclusion outlines the few areas of research that remain to be done on the subject of NiTiNOL SMAs’ machinability.
