Microstructural heterogeneity and bonding strength of planar interface formed in additive manufacturing of Al–Mg–Si alloy based on friction and extrusion
文献摘要：
Single-pass deposits of 6061 aluminum alloy with a single-layer thickness of 4 mm were fabricated by force-controlled friction- and extrusion-based additive manufacturing. The formation characteristics of the interface, which were achieved by using a featureless shoulder, were investigated and elucidated. The microstructure and bonding strength of the final build both with and without heat treatment were ex-plored. A pronounced microstructural heterogeneity was observed throughout the thickness of the final build. Grains at the interface with Cu,{213}<111>, and Goss orientations prevailed, which were refined to approximately 4.0 μm. Nearly all of the hardening precipitates were dis-solved, resulting in the bonding interface displaying the lowest hardness. The fresh layer, subjected to thermal processes and plastic deforma-tion only once, was dominated by a strong recrystallization texture with a Cube orientation. The previous layer, subjected twice to thermal pro-cesses and plastic deformation, was governed by P- and Goss-related components. The ultimate tensile strength along the build direction in as-deposited and heat-treated states could reach 57.0％ and 82.9％ of the extruded 6061-T651 aluminum alloy.
