摘要/Abstract

摘要： 采用SEM、HRTEM等试验方法,对2000 MPa级低成本复合强化超高强度AIR0509钢的二次硬化行为进行了研究,并与目前广泛应用于航空领域的AerMet100钢进行了对比。试验结果表明:试验钢具有明显的二次硬化现象,在535 ℃回火4 h时达到最佳强韧性配合,室温抗拉强度、屈服强度以及U型缺口冲击吸收能量分别为2020 MPa、1780 MPa和68 J,同淬火态相比屈服强度提高了480 MPa,这是由析出的复合强化相碳化物M₂C与金属间化合物β-NiAl共同作用的结果;此外,同AerMet100钢相比,AIR0509钢抗过时效的能力更强。

Abstract: Secondary hardening behavior of 2000 MPa level low cost compound strengthened ultra-high strength AIR0509 steel was studied by means of SEM and HRTEM, and compared with the AerMet100 steel widely used in the aviation field. The results show that the experimental steel exhibits an obvious secondary hardening phenomenon, the best combination of strength and toughness is obtained when tempered at 535 ℃ for 4 h, and the tensile strength, yield strength and impact absorbed energy are 2020 MPa, 1780 MPa and 68 J, respectively, the yield strength increases by 480 MPa compared to the quenched steel, which is dominated by the co-precipitation of both M₂C carbide and β-NiAl intermetallic. Moreover, the AIR0509 steel shows strong resistance to overaging compared to AerMet100 steel.

Key words: ultra-high strength steel, compound strengthening, secondary hardening, M₂C, β-NiAl
