Effect of Molybdenum on the Microstructure and Oxidation Behavior of Hot-Pressed TaCr2 Alloys
- 20 Downloads
Influence of molybdenum additions on the microstructure and corrosion resistance of powder alloys based on the TaCr2 Laves phase is studied. The phase composition of the alloys in different conditions is determined. Growth in the mass of the alloys is determined after 100-h oxidation at 900°C. The effect of the molybdenum additions on the structure and properties of the TaCr2 -base alloys is shown to be positive. An optimum composition is suggested.
