分析了电子束熔炼制备的不同相对密度的点阵结构的显微组织和力学性能。它们的显微组织进行了比较，散装零件。人们特别关注表面粗糙度对其弹性行为的影响。对这些结构进行了有效的化学蚀刻后处理。分析了两种结构的弹性力学行为。压缩测试表明，与相同相对密度的竣工结构相比，由化学蚀刻引起的粗糙度的重要降低导致相对刚度的增加。(C)2016爱思唯尔B.V.保留所有权利。
The microstructure and mechanical properties of lattice structures of various relative densities manufactured by Electron Beam Melting were analyzed. Their microstructure was compared to that of bulk parts. Special interest was given to the effect of surface roughness on their elastic behavior. An efficient chemical etching post-treatment was performed on these structures. The elastic mechanical behavior of both as-built and etched structures was analyzed. Compression testing revealed that the important decrease in roughness caused by chemical etching results in an increase in relative stiffness, in comparison with an as-built structure of the same relative density.
