文摘
- •
Solution strengthening caused by doping Ta is the main reason for hardness increase.
- •
The right amount of Ta alloying can increase the oxidation resistance.
- •
Too higher Ta content is not conducive to retard the formation of α-TiO2 during oxidation.
- •
The oxidation resistance is related with microstructure, phase transformation and stress.
