摘要

采用分离式霍普金森压杆对激光增材制造AerMet100超高强度钢沉积态和热处理态试样进行高应变率(1000~4200 s -1)动态压缩测试,并对微观组织和冲击断口进行了分析。结果表明:激光增材制造AerMet100钢具有明显的应变率敏感性,应变率强化效应显著;热处理可显著提高激光增材制造AerMet100钢的动态冲击性能,经885 ℃固溶(1 h)+(-73 ℃)深冷(1 h)+482 ℃回火(5 h)处理后,激光增材制造AerMet100钢试样表现出最佳的强韧性配比,动态冲击性能优异;当回火温度提高到494 ℃时,试样的动态压缩强度降低。

Abstract

Dynamic compression tests with a high strain rate (1000--4200 s -1) were carried out on the as-deposited and heat-treated samples of AerMet100 ultrahigh strength steel fabricated by laser additive manufacturing using a split Hopkinson pressure bar (SHPB), and the microstructures and impact fractures of the samples were observed. The results show that the strain rate sensitivity of the AerMet100 steel samples fabricated by laser additive manufacturing is high, and the strain rate hardening effect of the material is obvious. Heat treatment can improve the dynamic impact performance of the laser additive manufactured AerMet100 steel. After solid solution treatment at 885 ℃ for 1 h, oil quenching, cryogenic treatment at -73 ℃ for 1 h, and tempering at 482 ℃ for 5 h, the AerMet100 ultrahigh strength steel samples fabricated by laser additive manufacturing show the optimal combination of strength and toughness and an excellent dynamic impact performance. When the tempering temperature increases to 494 ℃, the dynamic compression strength of the samples decreases.
