Abstract

The heat treatment process parameters of GH4738 superalloy were optimized by Taguchi-Grey relational analysis method. Solution temperature (ST) and cooling rate (CR) were selected as controllable factors, while ultimate tensile strength (UTS), yield strength (YS), elongation (EL), and reduction of area (RA) as response variables. The multi-response optimization problem was converted into an equivalent value of grey relational grade (GRG) using grey relational analysis (GRA) based on the orthogonal test results. The optimal heat treatment process parameters for GH4738 superalloy were obtained, and the influence order of controllable factors on the response variables was determined.
