Explanation:
Detailed explanation-1: -Pure titanium metal undergoes an allotropic transformation that changes the crystal structure from the -phase to the -phase at about 885 °C. An allotropic transformation simply means the crystal structure changes when the material is heated above or cooled below a critical temperature called the transus temperature.
Detailed explanation-2: -allotropy, the existence of a chemical element in two or more forms, which may differ in the arrangement of atoms in crystalline solids or in the occurrence of molecules that contain different numbers of atoms.
