Thus, the addition of Zr alone into metal Ti should have no or very weak effects on its phase constitution, as Wang showed [ 24 ]. However, the addition of Zr together with other beta phase stabilizers of Ti alloys can enhance the stabilizing effect [ 25 ].

The first broad peak located at ~200–300 °C is associated with the desorption process of the chemisorbed oxygen on the material surface. The second oxygen desorption peak may be ascribed to the reduction of Fe 4+ to Fe 3+ at 300–650 °C [ 23 ].
