摘要/Abstract

摘要： 研究了固溶、时效和固溶+时效3种后续热处理工艺对结合金属沉积型3D打印316L不锈钢试样组织与性能的影响。结果表明,相比1000 ℃固溶处理和900 ℃时效处理,1000 ℃固溶+900 ℃时效处理使3D打印试样孔隙率下降更显著,并使条状碳化物向块状/短杆状转变,引起位错运动阻碍效应增强和应力集中程度下降,导致3D打印试样的抗压强度由热处理前的807 MPa提高至1207 MPa。

Abstract: Effect of three post-heat treatment processes of solution treatment, aging, and solution treatment+aging on microstructure and properties of bound metal deposition-based 3D printed 316L stainless steel specimens was studied. The results show that compared with 1000 ℃ solution treatment only and 900 ℃ aging treatment only, the process of 1000 ℃ solution treatment+900 ℃ aging leads to a reduction in porosity and the transformation of lamellar carbides into blocky and short rod-like structures, which enhance the obstruction effect on dislocation motion and reduce stress concentration, thereby increasing the compressive strength of the 3D printed specimens from 807 MPa before heat treatment to 1207 MPa.

Key words: bound metal deposition, 3D printing, 316L steel-polymer hybrid powder, heat treatment, microstructure and properties
