The phase transformation in the grinding process could have a significant impact on the processing performance of the products. Although grinding process can lead to high heating and strain rates, the current studies on the phase transformation typically consider temperature only that limits their accuracy. In this study, based on the phase transformation model, by conducting the micro-grinding experiment of maraging steel C250, the mechanism controlling impacts of heating and strain rates on phase transformation has been analyzed, and a new process optimization scheme to control phase transformation has been proposed. In this research was determinate main characteristic parameters of the phase transformation prediction model and influence of the heating rate parameters on the structure of the material. The main conclusions of this work are aimed increasing productivity, as well as criteria for optimizing the micro grinding process are defined.
