Nickel Titanium Alloys

nickel titanium alloys is a binary alloy composed of nickel and titanium, both elements having approximately equal atomic percentages (Nitinol 55 and Nitinol 60 are very common). Due to variations in temperature and mechanical stress, nickel-titanium alloys have two different crystal structures, called austenite and martensite.

What is nickel titanium alloys?

nickel titanium alloys is a nickel-titanium alloy with super elasticity and shape memory properties. Shape memory refers to the ability of a NiTi alloy to deform at a certain temperature and then recover its original, unshaped shape when heated above its transformation temperature. Superelasticity occurs in a narrow range of temperatures just above its transformation temperature; in this case, no heating is required to restore the unshaped shape, and the material exhibits tremendous elasticity, about 10-30 times that of ordinary metals.
