Nickel titanium, also known as nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages. Different alloys are named according to the weight percentage of nickel; e.g., nitinol 55 and nitinol 60 .

A three-component compatibility diagram will depict the stable phase of each pure component as the point at each corner of a ternary diagram. Additional points in the diagram represent other pure phases, and lines connecting pairs of these points represent compositions at which the two phases are the only phases present.
A binary phase diagram showing the most stable chemical compounds of titanium and nickel at different mixing ratios and temperatures. Phase transitions involving solutions and mixtures are more complicated than transitions involving a single compound.
The R-phase is a phase found in nitinol, a shape-memory alloy. It is a martensitic phase in nature, but is not the martensite that is responsible for the shape memory and superelastic effect. In connection with nitinol, "martensite" normally refers to the B19' monoclinic martensite phase, rather than the R-phase. The R-phase competes with ...

Phase diagram explaining how the pattern forms. First meteoric iron is exclusively composed of taenite. When cooling off it passes a phase boundary where kamacite is exsolved from taenite. Meteoric iron with less than about 6% nickel (hexahedrite) is completely changed to kamacite. Widmanstätten pattern, metallographic polished section
