Abstract  

A series of tests of fast-single pass-heavy deformation in low carbon steel was carried out using Gleeble 3500 thermal-mechanical simulation machine at the temperature above Ae3. The mechanical property of material before and after deformation was tested, and the fracture morphology was observed. Results denote that the deformation induced ferrite transformation (DIFT) above Ae3 is responsible for the ultra-fine grain size (about 3 μm). DIF can be induced when strain rate was 0.1 s−1. With the raise of strain rate, ferrite fraction becomes larger and the grain size smaller until DIF is saturated at the strain rate of 10 s−1. Grain refinement through DIFT leads to an increase in strength and hardness. For low carbon steel Q235, the yield strength can be improved from 250 MPa to 510 MPa and the tensile strength arrives at 625 MPa, and the plasticity decreases slightly which will remains in high level.
