Abstract: According to some configurations of the present disclosure, an alloy may include a composition that includes magnesium (Mg) that is approximately 5 to 12% by weight of the composition; manganese (Mn) that is approximately 0.1 to 2% by weight of the composition; and silicon (Si) that is approximately 0.3 to 3% by weight of the composition; and aluminum (Al) that is a balance of the composition. In one configuration, the composition may further include one or more of iron (Fe), titanium (Ti), zirconium (Zr), chromium (Cr), and/or yttrium (Y).

Abstract: Apparatuses and methods for in situ thermal treatment for PBF systems are provided. An apparatus for a PBF-based 3-D printer can include a heating element for heating a gas, wherein the heated gas is delivered via at least one port of the 3-D printer to conduct heat treatment on a build piece during printing. A method for thermal treatment in a PBF-based 3-D printer can include heating a gas and delivering it via at least one port of the 3-D printer arranged proximate a build piece to conduct heat treatment during printing. An apparatus for a PBF-based 3-D printer can include a temperature-regulating element for changing a temperature of a gas, at least one channel for delivering the gas to a plurality of ports, and a controller for determining gas temperatures and durations of application of the gas via different ones of the plurality of the ports.
