摘要
An example embodiment of a method is disclosed for making a component including a high entropy alloy (HEA). The method includes combining a reaction component with a powdered HEA precursor to form a solid HEA feedstock. The solid HEA feedstock is converted into a powder suitable for use as a powder feedstock in an additive manufacturing device and capable of sustaining a self-propagating high-temperature synthesis (SHS) reaction. At least a portion of the powder feedstock is additively manufactured into a preformed shape approximating a desired shape of the component. The preformed shape is filled with the HEA powder feedstock. The powdered HEA precursor in the preformed shape are ignited to induce the self-propagating high-temperature synthesis (SHS) reaction, thereby forming a stable HEA component approximating the desired shape.
