基金项目:This work was financially supported by the National Science and Technology Ministry to the research project 'Advanced industrialization technique of manufacture for carbon steel of 500 MPa grade' (No,2001AA332020).
摘    要:A low carbon steel was used to determine the critical strain εc for completion of deformation enhanced ferrite transformation (DEFT) through a series of hot compression tests. In addition, the influence of prior austenite grain size (PAGS) on the critical strain was systematically investigated. Experimental results showed that the critical strain is affected by PAGS. When γ→α transformation completes, the smaller the PAGS is, the smaller the critical strain is. The ferrite grains obtained through DEFT can be refined to about 3 μm when the DEFT is completed.
