초록
Nickel-Titanium (NiTi) is a material adopted in modern manufacturing sectors as its super elastic nature and shape memorybehaviour provides unique properties that can be integrated into complex applications and designs. The present investigationfocused on understanding the effects of cryogenic treatment composites i.e. Nickel-Titanium (nitinol) alloy reinforced withMulti-Wall Carbon Nanotubes (MWCNT). The novel nitinol of [49Ni-51Ti]100-x – X wt.% MWCNT (X = 0.5, 1.0, and 1.5) werefabricated using Powder metallurgy technique. The fabricated samples were characterized using Optical Microscope (OM),Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS), and X-Ray diffraction spectroscopy (XRD). Further, the fabricated samples were cryogenically treated at a temperature of -77 K in a liquid nitrogen atmosphere. Theoptical microstructural analysis result shows uniform distribution of MWCNT particles. The cryogenic treated samples weresubjected to analyse the hardness and high-temperature wear properties. The result clearly portrays that cryogenic treatedsamples improves the hardness and high temperature wear behaviour significantly compare to the non-cryogenic treatedsamples. The investigation of mechanical properties result shows that cryogenic treated sample such as 47.5Ni-49.5Ti-1.5MWCNT achieves a higher hardness about 262 HV.
