摘要：
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.
