| Abstract: | The effects of tempering temperature on the mechanical properties, microstructure and precipitation behavior of SA533B steel were investigated by utilizing optical microscopy and transmission electron microscopy. The results show that the optimized comprehensive mechanical properties were obtained after quenched at 880℃ and tempered at 680℃, and yield strength, ultimate tensile strength, total elongation and impact energy can reach 635MPa, 750MPa, 21% and 120J. |
