Laser powder bed fusion produced AlSi10Mg parts are being explored as a potential means for replacement of castings in aerospace applications. Maximizing the mechanical properties of this alloy is desirable to meet or exceed the performance of castings made of alloys such as A356. Here the results will be presented from a design of experiments examining existing specified precipitation heat treatments along with variations of those heat treatments with various quenchants including cold water, heated water, glycol, and forced air. Specimens with and without hot-isostatic pressing (HIP) are used to generate aging curves at 160C and 205C. It will be shown that HIP before precipitation hardening will be shown to increase tensile properties and accelerate artificial aging. An empirical model will be shown linking hardness to aging conditions.
