研究了激光选区熔化AlSi 10 Mg合金的固溶处理和时效硬化过程。建立了对显微组织和硬度的影响，以及对Si颗粒的尺寸和密度的影响。虽然硬度根据处理时间而变化，但最大硬化效果福尔斯低于具有其特征性精细显微组织的完工零件的硬度。这是由于加强机制的差异。(C)矿物、金属和材料协会和ASM国际2015
Precipitation hardening of selective laser melted AlSi10Mg was investigated in terms of solution heat treatment and aging duration. The influence on the microstructure and hardness was established, as was the effect on the size and density of Si particles. Although the hardness changes according to the treatment duration, the maximum hardening effect falls short of the hardness of the as-built parts with their characteristic fine microstructure. This is due to the difference in strengthening mechanisms. (C) The Minerals, Metals & Materials Society and ASM International 2015
