The research on analyzing of phase change on binary alloy Pt1-X Mn x (x=17.5 at. %) system had been performed by diffraction and resistivity measurements. The purpose of this experiment is to investigate the change of order-disorder phase transition and its critical temperatures. The polycrystal samples of nominal concentrations of 17.5 were prepared from 99.999 % of pure platinium and 99.99 % of pure manganese. This sample was heat-treated separately at 1150°C for 2 days to remove strains. Then, the sample was quenched by dropping quickly into iced water to get a disordered state. X-ray diffractometer experimental results shows that samples contained 17.5 at. % Mn and heat-treated at the temperature of 1150°C for 2 days were in the disorder state. Meanwhile, ordered state was seen on the sample of 17.5 at. % Mn, heat-treated at 800°C for 10 days.
