False-colour electron diffraction pattern of a binary alloy of 90% titanium and 10% nickel. This forms the basis of a family of other alloys, which may contain between 3 and 6 other alloying elements in small amounts. Such alloys have a diversity of use depending on the other alloying elements. Some are used in the aerospace industry, others in medical prostheses and in salt-water resistant components. The sample here is a combination of the beta and omega phases of the alloy, thermally quenched from a temperature of 950 Celsius.
