Abstract

The vacuum arc remelting (VAR) process is widely used to improve the cleanliness and refine the structure of standard air melted or vacuum induction melted (VIM) ingots and also used in the triplex production of superalloys. This article illustrates the VAR process and the capabilities and variables of the VAR process. It also presents a discussion on the melt solidification, resulting structure, and ingot defects. The article concludes with a discussion on VAR process of superalloy, and titanium and titanium alloy.
