摘要/Abstract

摘要： 利用激光选区熔化(Selective laser melting,SLM)增材制造技术制备了GH3536镍基高温合金,研究了直接时效、固溶及热等静压处理对SLM合金组织和裂纹的影响规律,利用XRD、SEM、EPMA、EBSD、TEM等方法表征相组成和组织演变。结果表明:SLM态组成相为γ相,经固溶和时效热处理后,晶界析出针棒状和片层状相,EPMA结果表明这些相富含C、Cr、Mo,主要组成为Laves相和碳化物相;SLM态试样经固溶热处理后,合金元素扩散加强,熔池边界逐渐消失;SLM态平均晶粒尺寸13.18 μm,经高温热处理后,合金晶粒发生再结晶,平均晶粒尺寸减小,经固溶处理后平均晶粒尺寸为12.01 μm,而经热等静压处理(1050℃/3 h/120 MPa)后平均晶粒尺寸为10.87 μm。SLM态试样中存在10~100 μm的微裂纹,裂纹起源于熔池内部并贯穿熔化道;经直接时效和固溶热处理后微裂纹未明显改善,而热等静压则可完全消除微裂纹。

Abstract: GH3536 superalloy is fabricated by selective laser melting (SLM), its microstructure evolution and crack variation under various heat treatments are studied. Microstructure evolution and phase identification are conducted by XRD, SEM, EPMA, EBSD, and TEM. the results indicate that the main constituent phase of specimens fabricated by SLM is γ phase. Needle-rod and lamellar phases which are rich in C、Cr and Mo elements are formed inside the grains, as well as the grain boundaries after heat treatment, These phases are mainly composed of Laves phase and carbides. The melt pool boundaries of specimens fabricated by SLM gradually become shallow and disappear after heat treatment, because of the improved diffusion effect of alloying elements. The average grain size of specimens fabricated by SLM is 13.18 μm, and it decreases to 12.01 μm after solution treatment, and the grain size is obviously refined to 10.87 μm after hot isostatic pressing, as a result of recrystallization. Micro-cracks can be observed in the matrix after SLM process, and the length is measured ranging from 10 to 100 μm. These cracks are found to originate inside the melt pool, and penetrate through the melt pool. After direct aging heat treatment and solution heat treatment, the size and distribution of micro-cracks do not improve significantly. However, after hot isostatic pressing, the micro-cracks are almost eliminated.

Key words: selective laser melting, GH3536 superalloy, heat treatment, HIP, microstructure
