Mechanical properties of an induction-slag-melted Ti-6Al-4V alloy
The Albany Research Center (ARC) of the Department of Energy is investigating a means to form useful wrought products by direct and continuous casting of titanium bars using cold-wall induction melting. An investigation to compare the mechanical properties of a commercial Ti-6Al-4V ingot with a cold-wall induction slag melted Ti-6Al-4V ingot was performed to determine if the slag additions used to improve the surface finish adversely affect ingot quality, i.e., microstructure and mechanical properties. Room temperature tensile, Charpy, and fatigue tests were performed. The experimental alloy was found to have slightly higher strengths, and slightly lower ductilities, impact energies, and fatigue life than the commercial Ti-6Al-4V ingot, although all values were found to be similar to typical handbook properties. Slag additions do not appear to detrimentally affect the mechanical properties of Ti-6Al-4V ingots prepared in a cold-wall induction slag furnace.
