Abstract

Different annealing process and the same quenching tempering process were used to execute the heat treatment for Q235Ni0.1Zr0.1Y0.1 new low alloy steel structure, and the microstructure of the steel structure was observed and the mechanical properties and damping performance were analyzed. The results show that, compared with 460 ℃ annealing, the mechanical properties and damping performance of the steel structure reduce after annealed at 600 ℃, the tensile strength, yield strength and break elongation is decreased by 7.1% , 12.2% and 9.8% , respectively. As the frequency of 1 Hz, the damping performance is decreased by 71.4%. After stepping-annealing, the tensile strength, yield strength and break elongation of the steel structure is increased by 14.3%, 13.4% and 12.8%, respectively. As the frequency of 1 Hz, the damping performance is increased by 321.4%.
