In order to improve the recrystallization resistance and the mechanical properties of molybdenum, TiC particle-reinforcement composites were sintered by SPS. Powders with TiC contents between 6 and 25 vol.% were prepared by high energy ball milling. All powders were sintered both at 1600 and 1800°C, some of sintered composites were annealed in hydrogen for 10h at 1100 up to 1500°C. The powders and...
The present study describes the effect of thermomechanical treatments on the microstructure of molybdenum–titanium and the molybdenum alloy TZM (0.5wt.% Ti, 0.08wt.% Zr). These alloys were processed by a powder metallurgical route including extensive rolling at temperatures above 1200°C achieving deformation degrees of 2.87 (logarithmic). The alloys exhibit a distinct increase in yield stress without...
