چکیده انگلیسی
Carbide evolution was investigated in order to find methods to reduce the carbide precipitation because it lowers the ductility of metal injection moulded -Ti alloys. Comparing Ti-22Nb and Ti-22Nb-2/10Zr alloys, the crystal structure of carbides is unchanged, but the lattice parameter of -Ti increases, then carbide fraction slightly decreases. Dissolution of carbides occurs fast around -transus temperature via short circuit diffusion but it becomes slow with decreasing temperature because of uniform atomic detachment. Based on these results, a multiple step treatment was proposed which in conjunction with grain refinement by adding Y/Y2O3, can significantly decrease the carbide fraction of Ti-22Nb-10Zr-xY/Y2O3.
