Alloying molybdenum is the main way to improve the performance of other alloying elements by doping excellent properties can be prepared molybdenum-based composite materials. According to strengthen type doped molybdenum-based alloys can be divided into solid solution strengthening molybdenum alloy, dispersion strengthened molybdenum alloy, K bubble strengthened molybdenum alloy.
1. Molybdenum alloy solid solution strengthening. Molybdenum matrix add other alloying elements and the substrate to form a solid solution to improve the mechanical properties of a class of solid solution strengthening alloy molybdenum alloy called. This category mainly Mo-Ti alloy alloy, Mo-Zr alloy, TZM alloy, TZC alloys and Mo-Re alloys.
2. The dispersion strengthened molybdenum alloys. By adding alloying elements to form dispersed uniformly distributed in the molybdenum matrix second particle, one can impede dislocation motion increased dislocation density on the other hand will hinder bit grain grown during sintering molybdenum matrix grain finer so as to achieve fine grain strengthening effect. Dispersion strengthened type molybdenum alloy mainly molybdenum alloy and alumina doped with rare earth elements molybdenum alloys.
3.K bubble molybdenum alloy reinforced.K foam reinforced Si-Al-K in this category especially molybdenum alloys doped molybdenum alloy. The main preparation is powder metallurgy. Preparation of mixed powder by liquid - solid doping.
