| Abstract | Influence of hot rolling conditions on the mechanical properties of hot rolled TRIP steel was investigated. Thermomechanical control processing (TMCP) was conducted by using a laboratory hot rolling mill, in which three different kinds of finish rolling temperatures were applied. The results show that polygonal ferrite, granular bainite and larger amount of stabilized retained austenite can be obtained by controlled rolling processes. The finer ferrite grain size is produced through the deformation induced transformation during deformation rather than after deformation, which affects the mechanical properties of hot rolled TRIP steel. Mechanical properties increase with decreasing finish rolling temperature due to the stabilization of retained austenite. Ultimate tensile strength (UTS), total elongation (TEL) and the product of ultimate tensile strength and total elongation (UTSxTEL) reaches optimal values (791 MPa, 36% and 28 476 MPa%, respectively) when the specimen was hot rolled for 50% reduction at finish rolling temperature of 700 degrees C. |
