| Abstract: | Melting characteristics of Ti2AlNb-based alloy are discussed.Structural principle of ISM equipment and melting techniques are introduced. Effects of alloying elements mix methods and vacuity in chamber on uniformity and alu-minum volatilization loss of the ingot are investigated. Experimental results show that ingot made of Ti2AlNb-based alloy has good uniformity by ISM, and the volatilization weight loss rate of aluminum varies from 5% to 10% with different ISM processes. |
