Sol NiTi alloy also known as Nitinol is an alloy with a nearequiatomic composition ie 4951 of nickel and titanium NiTi belongs to the class of shape memory alloys that can be deformed at a low temperature and are able to recover their original permanent shape when exposed to a high temperature The shape memory effect of Nitinol is related to its martensitic transformation In fact at high temperature the atoms are arranged in an orderly manner in a BCC crystal structure ie austenitic phase In this phase the alloy is resistant to twisting and bending At low temperature NiTi alloy exhibits a monoclinic distorted crystal structure that is a martensitic phase At this stage the alloy can be easily deformed The temperature at which the austenitic phase transforms into a martensitic one is called the transformation temperature The atomic percentage composition is important in determining the shape memory effect at body temperature in fact the presence of a higher content of nickel even by 01 can induce a decrease in the transformation temperature and an increase in yield strength of the alloy See Answer
