METHOD OF PRODUCTION OF STEEL PARTS BY QUENCHING WITH TEMPERATURE EQUALIZATION AT MS
This invention generally relates to a method for producing steel parts by creating multiphase microstructures within the steel parts. Typically, the microstructures comprise low-stress martensite with increased ductility and stabilized retained austenite. The microstructures may be formed by cooling...

| description | This invention generally relates to a method for producing steel parts by creating multiphase microstructures within the steel parts. Typically, the microstructures comprise low-stress martensite with increased ductility and stabilized retained austenite. The microstructures may be formed by cooling the steel parts to a temperature around the martensite start temperature (Ms) and subsequently holding the steel part at a temperature around the Ms in order to equalize the temperature throughout the steel part. Afterwards, the formation of the microstructures and the desired properties is completed by subjecting the steel part to a final cooling in still air. |
