| Abstract: | The heat treatment process for X20Cr13 steel used for turbine blades was investigated through an orthogohal test so as to make the heat treatment process of steel optimized. Besides,the steel was cooled at different rates after tempering to reveal the effect of cooling rate on its temper brittleness. As a result, the optimum heat treatment process for X20Cr13 steel lies in quenching in oil or in forced air and tempering at 670 ℃follwed by cooling in forced air. |
