A method for use in additive manufacturing of a three-dimensional workpiece is described. The method includes depositing material onto a substrate to form a shape of the workpiece in accordance with an additive manufacturing process; determining a thermal characteristic of at least a portion of the workpiece during the additive manufacturing process; determining that the thermal characteristic of at least the portion exceeds a threshold associated with the portion; adjusting a cooling parameter of a cooling flow to be applied to the workpiece responsive to determining that the thermal characteristic of at least the portion exceeds the threshold associated with the portion; and applying the cooling flow with the adjusted cooling parameter to at least the portion of the workpiece.

A method for making an aluminum alloy includes steps of (1) weighing out starting materials to achieve a mass of material having a composition that includes aluminum, about 1.8 to about 5.6 percent by weight copper, about 0.6 to about 2.6 percent by weight lithium, and at least one of lanthanum up to about 1.5 percent by weight, strontium up to about 1.5 percent by weight, cerium up to about 1.5 percent by weight, and praseodymium up to about 1.5 percent by weight; (2) loading said starting materials into a crucible; (3) inserting said crucible into a chamber; (4) evacuating said chamber to a predetermined vacuum level; (5) melting said starting materials to form a molten mass; and (6) casting said molten mass into a mold.

Assessing material strength for additive manufacturing is provided. The method comprises calibrating a baseline electrical resistivity of a multi-phase additive material for a set dislocation density as a function of phase fraction and phase composition, wherein individual phases of the material have different electrical resistivity values. After the additive material has undergone a number of heating and cooling cycles during additive manufacturing the additive material is characterized for phase fraction, phase composition, and electrical resistivity. Dislocation density of the additive material is then determined according to electrical resistivity after additive manufacturing, accounting for effects of phase fraction and phase composition determined by characterization.
