Research on the volatility law of Mn element in TC2 titanium alloy
The experiments and detection analysis were conducted on the degree of Mn volatilization in different parts of the outer circle of the ingot and the cross-section of the head and tail of the secondary ingot after the primary and the secondary vacuum arc remelting(VAR)processes in TC2 titanium alloy.The results show that after the primary VAR,the volatilization loss of the local Mn elements in the ingot is 6%;after the secondary VAR,the volatilization loss of Mn element is between 40%and 50%;and the composition uniformity of Mn in the cross-section of the tail is inferior.
