【Abstract】 The paper studies the effect of carburizing treatment on the properties of TiAl alloy at room temperature. It is found that the bend strength, deflection and bend toughness of the alloy increase greatly after carburizing treatment, indicating that the sar face chemico-thermal treatment is a good way for improving mechanical properties of TiAl base alloy.更多还原
