Vacuum arc remelting: An overview
Abstract
Vacuum arc remelting (VAR) is a casting process for producing uniform ingots. This paper discusses: arc physics and behavior, metal transfer and electrode gap measurement, boundary conditions on crucible wall, and pool dynamics and macrosegregation. Materials discussed are Inconel 718 and U-6% Nb alloy.
