The identification of residual stresses (RS) in components made by selective laser melting (SLM) is necessary for subsequent technological optimization. The presented research is devoted to evaluating the influence of the combination of laser power (P), scanning velocity (v) and the rarely considered number of layers (n) on surface residual stresses in SLM stainless steel SS 316L. Experimental parameters were set based on the Design of Experiment (DoE) method, with follow-up X-ray diffraction (XRD) measurements and data processing using analysis of variance (ANOVA) and regression analysis. The obtained data are a valuable stepping-stone for the subsequent design of research focused on the application of sustainable eco-friendly Abrasive Water Jet (AWJ) peening for RS modification in the evaluated material.
识别选择性激光熔化（SLM）制造的部件中的残余应力（RS）对于后续的工艺优化是必要的。本研究致力于评估激光功率（P）、扫描速度（v）以及很少被考虑的层数（n）的组合对SLM不锈钢SS 316L表面残余应力的影响。实验参数基于实验设计（DoE）方法设置，随后进行X射线衍射（XRD）测量，并使用方差分析（ANOVA）和回归分析进行数据处理。所获得的数据是后续研究设计的重要基础，该研究聚焦于应用可持续环保的磨料水射流（AWJ）喷丸处理来改变所评估材料中的残余应力。
