Variations in local processing parameters and conditions in additively manufactured materials make mechanical properties difficult to characterize. Microtensile testing is providing a wealth of information on these local property variations. Here we utilize spatial autocorrelation techniques to show autocorrelation of grain sizes and mechanical properties with build height in a specially-designed, additively manufactured AlSi10Mg part. This result suggests that, at least in some cases, an interplay between local part geometry and the fabrication process occurs that affects local mechanical properties.

增材制造的AlSi10Mg零件的制造高度效应的方差分析

增材制造材料中局部加工参数和条件的变化使机械性能难以表征。显微拉伸测试提供了有关这些局部特性变化的大量信息。在这里，我们利用空间自相关技术来显示经过特殊设计的，添加制造的AlSi10Mg零件的晶粒尺寸和机械性能与制造高度的自相关。该结果表明，至少在某些情况下，局部零件的几何形状与制造过程之间会发生相互作用，从而影响局部的机械性能。
