Alloy formation during the sintering of molybdenum-chromium powder mixtures
- 16 Downloads
A molybdenum-chromium alloy forms through preferential diffusion of chromium into pure molybdenum, with the formation of a stable molybdenum-base intermediate solid solution, followed, after the disappearance of pure molybdenum, by diffusion of chromium into the intermediate solid solution, resulting in a steady increase in the latter's concentration. The picture of alloy formation in the molybdenum-chromium system differs radically from that in a system exhibiting full intersolubility of components in the solid state, such as the copper-nickel system.
