Effect of Stepwise Cooling on the Microstructure and Mechanical Properties of a 1300 MPa‐Grade High‐Strength Steel for Engineering Machinery

This study investigated a 1300 MPa‐grade engineering‐machinery steel processed by four stepwise cooling routes with intermediate cooling temperatures of 800 or 850 °C and final cooling transition temperatures of 500 or 650 °C. The cooling route markedly affected the bainite/marte...
