Abstract

Mechanical properties of Titanium-zirconium-molybdenum (TZM) and La₂O₃ doped TZM alloys under compression were tested at 1000 °C and 1200 °C. Microstructure of TZM and La₂O₃ doped TZM alloys after compressing was characterized by scanning electron microscopy. The effects on La₂O₃ doping on the high temperature deformation behavior and microstructure evolution of the TZM alloy were analyzed. Results show that La₂O₃ doping can refine the grain size of TZM alloy. La₂O₃ doping changes fracture model of TZM alloy. TZM alloy exhibits mainly intergranular fracture, while the La₂O₃ doped TZM alloy exhibits both intergranular and transgranular fracture mode.
