Influence of deposition strategy of structural interface on microstructures and mechanical properties of additively manufactured Al alloy

Mechanical properties of the structural interface are significantly important for the wire + arc additively manufactured (WAAM) component who keeps the substrate as a part. Two deposition strategies using power sources of pulse advanced cold metal transfer (CMT-PA) and pulse metal inert gas (MIG-P) as the first layer were designed to build WAAM 2319 Al alloy walls. The microstructure and mechanical properties of the structural interfaces and the...
