| Abstract: | A new way to fine steel structure has been developed. It is the austenite-ferrite-repeating deformation. The effect of austenite-ferrite-repeating deformation on the mechanical properties of steel Q235 has been investigated by introducing a thermal simulation sample which has been worked out by ourselves. The results of the study indicate that the mechanical properties of steel Q235 are enhanced by this new method. |
