摘要

Abstract

The mechanical anisotropy of selective laser melted (SLM) aluminum alloys resulting from heterogeneous grain structures is still not fully understood due to lacking study of grain orientation related mechanical response. Here

by introducing in-situ EBSD tensile method

the orientation induced anisotropy coefficient K

related to the deformation-induced grain rotation was revealed by excluding effects of grain size and grain aspect ratio. Compared with traditional mechanical properties models by Taylor factor M

it was found that the orientation 001 in as-built and 102 in heat treatment contributed the most yield strength anisotropy

and introducing K

predicts the mechanical anisotropy more accurately.
