Abstract

Studies of the physical and technical properties of Pt-Mo alloys were carried out. The maximum solubility limit of Mo in α-phase (Pt-phase) is 15%, and the lattice parameter of α-phase (f.c.c.) lowers with the increase of the Mo content. Cold-working can be applied to α-phase alloys which contain less than 6% of Mo, and their annealing temperature is above 1,100°C. The oxidation of Pt-Mo alloys has been studied. At high temperature i.e., above 1,000°C, MoO3 volatilizes away as rapidly as it is formed, and the β-phase transforms into α-phase by oxidation in air. A preferred oxidation of Mo in α-phase was observed by prolonged heating in air, and it oxidized according to a logarthmic-rate law.
