摘要/Abstract

摘要： 将Al-6.15Zn-1.41Mg-1.45Cu合金在477 ℃固溶1 h后,基于脉冲磁场对Al-6.15Zn-1.41Mg-1.45Cu合金进行双级时效处理,通过改变时效时间,且与常规双级时效组织和性能对比分析,研究脉冲磁场对Al-6.15Zn-1.41Mg-1.45Cu合金时效过程中析出相和力学性能的影响,并结合动力学分析Al-6.15Zn-1.41Mg-1.45Cu合金在脉冲磁场双级时效过程中析出相加速析出的扩散机制。采用SEM观察Al-6.15Zn-1.41Mg-1.45Cu合金析出相和拉伸断口形貌,并进行力学性能测试。结果表明,脉冲磁场在Al-6.15Zn-1.41Mg-1.45Cu合金经时效过程中,提高扩散系数,提高析出相的形核率,使得时效后,基体中出现弥散细小的析出相。经脉冲磁场双级时效处理(121 ℃×90 min+177 ℃×60 min)后,抗拉强度为495.43 MPa,硬度为156.3 HV5,相比于常规的双级时效处理,抗拉强度提升20.83%,硬度提升17.89%,时效保温时间缩短87.5%。

Abstract: After solution treatment at 477 ℃ for 1 h, the Al-6.15Zn-1.41Mg-1.45Cu alloy was treated by two-stage aging based on pulsed magnetic field. The effect of pulsed magnetic field on the precipitated phase and mechanical properties of the Al-6.15Zn-1.41Mg-1.45Cu alloy during aging was studied by changing the aging time and comparing with the conventional two-stage aging structure and properties. The diffusion mechanism of precipitated phase accelerated precipitation in the Al-6.15Zn-1.41Mg-1.45Cu alloy during two-stage aging in pulsed magnetic field was analyzed with kinetics. The precipitation phase and tensile fracture morphology of the Al-6.15Zn-1.41Mg-1.45Cu alloy were observed by SEM, and the mechanical properties were tested. The results show that the pulsed magnetic field increases the diffusion coefficient and nucleation rate of the precipitated phase during aging process of the Al-6.15Zn-1.41Mg-1.45Cu alloy, resulting in the appearance of diffusely fine precipitated phases in the matrix after aging. After two-stage aging pulsed magnetic field (121 ℃×90 min+177 ℃×60 min), the tensile strength is 495.43 MPa, and hardness is 156.3 HV5. Compared with the conventional two-stage aging treatment, the tensile strength increases by 20.83%, hardness increases by 17.89% and the aging holding time reduces by 87.5%.
