The microstructural evolution of Laves phase in 9Cr–3W–3Co steel under long-term isothermal treatment has been experimentally investigated this paper. As distinguished SEM-BSE images, the mean size and area fraction particles are statistically measured. With help thermodynamic calculation analysis, weight precipitates at equilibrium state aging for up to 10 000 h is analyzed. W matrix depleted; enhances formation coarsening phase. This might be explanation softening behavior deterioration...
Creep rupture tests of 9Cr-3W-3Co steel were conducted in the range 120 to 200 MPa at 650 °C. The influence stress on microstructure evolution was investigated detail. In high regime, a large density dislocation generated and induced precipitation fine dispersive particles. However, lower stresses, transformation from martensite laths size subgrains coarsening precipitates took place due significant recovery loss pinning effect during long term exposure. Thermodynamic results revealed...

In order to research the heat treatment process of hydrogen 12Cr2Mo1VR steel, small furnace 50 kg was smelted and rolled. The influence cooling rate on microstructure steel studied, quenching tempering explored. It is found that austenitizing temperature should be above 875°C in obtain better solid solution strengthening effect avoid two coarsening caused by undissolved phase after quenching. serious M6C with coarse tempering, higher than 706°C. After comparing impact properties tensile...
