title: [The influence of Ce on microstructures and mechanics performances of Ti-Fe-Mo-Mn-Nb-Zr alloys].
abstract: The influences of Ce on the microstructure and mechanics performances of Ti-Fe-Mo-Mn-Nb-Zr alloys were studied and presented in this paper. The microstructure of no-Ce Ti-Fe-Mo-Mn-Nb-Zr alloy was thick, long and dendritic, and the microstructure of alloy was fined by Ce. With the increase in Ce wt%, the microstructure became equiaxial gradually. Hardness decreased with the increase in Ce wt%. The compression yield strength became greater with the increasing of Ce wt%, but after the Ce wt% increased to a certian degree, the compression yield strength became smaller with the further increasing of Ce wt%. This phenomenon was explained in the light of bond energy and X-ray diffraction experiment. X-ray diffraction experiment showed that the alloys were beta-Ti.
