| Abstract: | In this paper, the Gleeble 1500 heat/mechanics moulding experimental setup is used to make hot compressive test on the steel so as to study the influence of rate and temperature of deformation on the grain character of medium carbon CrNiMoV steel's hot deformed Austenite. The results show that lower temperatures or higher rates of deformations can lead to finer grain. These results are very useful to understand the rule of high temperature structure of the medium carbon CrNiMoV steel varied with conditions. Our results can also provide practical instructions to the design of reseaonable process, the efficient control of the product's structural properties and improvement of product's quality. |
