This Alloy Can Remember How It Looks!!!😱
Introduction First discovered by William J. Buehler with Frederick Wang in 1959 during their research at Naval Ordnance Laboratory. It is an alloy of Nickel and Titanium called Nitinol (NiTi). It is an acronym for Ni- Nickel, Ti-Titanium, Nol-Naval Ordnance Laboratory. It has main properties like ‘Super elasticity’ and ‘shape memory’ (due to this property it is also called a Shape memory alloy). Let us go into details of the properties of Nitinol. Why Nitinol is called a shape memory alloy (SMA)? Nitinol is called a shape memory alloy because it regains its predetermined shape when it is heated above a certain temperature generally known as transformation temperature, irrespective of the shape from which it is being transformed. i.e., it actually remembers its shape! This can also be called ‘The shape memory effect’. In simple words if a straight wire is deformed by winding it into a coil, then heating this coil to a certain temperature by placing it into a hot water bath ‘h
