Abstract
The heat treatment for a new designed Ni-based single crystal superalloy was investigated. The solution heat treatment was confirmed as 1260 °C/2 h + 1280 °C/4 h, AC through differential scanning calorimetry (DSC) curves and incipient melting experiments. The aging heat treatment was determined as 1120 °C/4 h, AC + 870 °C/32 h, AC according to the high temperature stress rupture tests for samples aging at different temperatures. Results showed that the eutectic was completely dissolved after solution heat treatment. The γ′ phase was uniformed in suitable size after aging heat treatment. The stress rupture test at 1070 °C/140 MPa showed the rupture life of alloy after heat treatment was 163.25 h. The segregation degree of alloying elements after heat treatment was decreased obviously.
