| 英文摘要 | In this study, molybdenum alloy with the nanoscale second phase dispersion distribution (NM-TZM) was prepared by powder metallurgy. Despite maintaining a high yield strength of 893 MPa, the elongation of the asforged MN-TZM alloy has been increased to 25.3 %. In addition, the recrystallization start temperature of NM-TZM alloy was increased by 100 degrees C, reaching 1400 degrees C. The nanoindentation results indicate that the NMTZM alloy still exhibits a high hardness of 4.40 GPa following annealing at 1400 degrees C. The addition of nanoscale second phase can improve the ductility and high temperature stability of the alloy by coupling with dislocations and grain boundaries. A new model for the synergistic effect of grain boundaries and intragrains to improve ductility is proposed, which provides insight into the reason behind the high ductility of NM-TZM. |
