| Abstract |
The vacuum refining of nickel base Rene´ 80 was studied by using a 2㎏ laboratory vacuum induction melting apparatus. It was possible to reduce the sulfur content of superalloy Rene´ 80 to below 2 ppm by strong induction stirring of melt and a use of calcia lined crucible. At initial carbon contents below 0.04%, the degree of decarburization after first refining and second refining were 77% and 57%, respectively. At initial carbon contents above 0.04%, the degree of decarburization decreased with increasing initial carbon content. |
