Abstract

A method of high temperature thermo-mechanical treatment (TMT) and subsequent cold (heat) treatment was applied to a novel ultra-high-strength steel (G33 steel). The effect of different process parameters on microstructure and mechanical properties of quasi-static (10-3s-1) tensile samples of G33 steel was investigated. The results show that the optimum treatment process of G33 steel is high temperature (1078℃) TMT with 50% deformation + cooled at -73℃ for 1h + tempered at 200℃ for 2h, and after the process, the yield strength of G33 steel is 1685MPa, the ultimate tensile strength is 2130MPa, and the total elongation is 14.0%.
