摘要/Abstract

摘要： 通过光学显微镜(OM)、扫描电镜(SEM)、透射电镜(TEM)及显微硬度计对选择性激光熔融(SLM)制备的7175铝合金经过固溶与双级时效处理后的显微组织、硬度及相变进行了探究。试验结果表明,未经处理的7175合金显微组织展现出显著的通道间非均匀性,而经过固溶与双级时效处理后,该合金表现出均匀且细小的显微组织,通道结构消失。热处理后合金的硬度相较于热处理前(83 HV0.3)有所提高,平均达到约162 HV0.3。晶界处的沉淀S相(Al₂CuMg)及θ相(Al₂Cu)为合金硬度的强化相,提供了弥散强化和沉淀强化的效应。

Abstract: Microstructure, hardness and phase transformation of 7175 aluminum alloy prepared by selective laser melting(SLM) after solution treatment and two-stage aging were investigated by means of OM, scanning electron microscope (SEM), transmission electron microscope (TEM) and microhardness tester. The experimental results reveal that the microstructure of the SLMed 7175 alloy shows significant inter-channel heterogeneity. After solution and two-stage aging treatment, the alloy shows uniform and fine microstructure, and the channel structure disappears. The hardness of the alloy after heat treatment is higher than that of the SLMed alloy (83 HV0.3), reaching an average of about 162 HV0.3. The precipitation S phase (Al₂CuMg) and θ phase (Al₂Cu) at the grain boundaries are the strengthening phases of alloy hardness, which provides the effect of dispersion strengthening and precipitation strengthening.

Key words: 7175 aluminum alloy, selective laser melting(SLM), heat treatment, microstructure, mechanical properties
