Study on the Microstructure Evolution and Tungsten Content Optimization of 9Cr-3W-3Co Steel

Study on the Microstructure Evolution and Tungsten Content Optimization of 9Cr-3W-3Co Steel

Creep rupture tests of 9Cr-3W-3Co steel were conducted in the range of 120 to 200 MPa at 650 °C. The influence of stress on microstructure evolution was investigated in detail. In the high stress regime, a large density of dislocation was generated and induced precipitation of fine and disp...
