形变诱导铁素体相变 DIFT ; deformation induced ferrite transformation
了形变诱导铁素体相变 deformation induced ferrite transformation
形变参数对相变过程有着显著的影响，奥氏体化温度决定了奥氏体原始晶粒尺寸同样影响着形变诱导铁素体相变过程。
Deforming parameters can have remarkable effect and the austeniting temperature can determine the original austenite grain size, consequently influence the process of DIFT.
