Microstructure and Thermodynamic Analysis of Ti-Nb-Cr-C Doped Molybdenum Alloy AITranslate
Abstract AITranslate
The Ti-Nb-Cr-C doped molybdenum alloy was prepared by powder metallurgy, and its microstructure, particle size and composition were analyzed. Thermodynamics was discussed of oxide generation during ball milling and carbide formation during sintering. The results show that the second phase particles are mainly distributed on the grain boundary, and also distributed inside the grain when Nb content is eno- ugh. The second phase mainly contains Nb,Ti and C,possibly being composite carbides of Nb and Ti based on the thermodynamics analysis. The second phase particles can refine the grains of molybdenum alloy, and the effect of grain refinement is strongest with Nb content of 3 %. Cr exists in molybdenum alloy mainly in the form of solid solution.
