Abstract
Official abstract text for this publication.
A method for making a component comprising a high entropy alloy (HEA) includes combining a reaction component with a powdered HEA precursor, igniting the combination of the reaction component and the powdered HEA precursor to induce a self-propagating high-temperature synthesis (SHS) reaction and to form a solid HEA feedstock, converting the solid HEA feedstock into a powder HEA feedstock, and additively manufacturing at least a portion of the powder feedstock into a HEA component or HEA preformed shape approximating a desired shape of the component.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for making a component comprising a high entropy alloy (HEA), the method comprising: combining a reaction component with a powdered HEA precursor; igniting the combination of the reaction component and the powdered HEA precursor to induce a self-propagating high-temperature synthesis (SHS) reaction and to form a solid HEA feedstock; converting the solid HEA feedstock into a powder HEA feedstock, wherein converting the solid HEA feedstock into a powder HEA feedstock comprises grinding the HEA feedstock into a powder; and additively manufacturing at least a portion of the powder feedstock into a HEA component or HEA preformed shape approximating a desired shape of the component; wherein the HEA feedstock comprises nickel, cobalt, chromium, iron, aluminum, titanium, zirconium, niobium, molybdenum, and tantalum, wherein the aluminum, titanium, zirconium, niobium, each have a first molar percentage, and the molybdenum and tantalum each have a second molar percentage, wherein each first molar percentage is approximately equivalent, and wherein each second molar percentage is approximately half of each of the first molar percentage. 2. The method of claim 1 , wherein the at least portion of the powder feedstock is additively manufactured into a HEA preformed shape approximately a desired shape of the component and further comprising: performing a hot isostatic processing (HIP) step on the HEA preformed shape to form the HEA component of the desired shape. 3. The method of claim 2 , wherein the HIP step is performed in a mold. 4. The method of claim 3 , wherein the mold is additively manufactured to match the desired shape. 5. The method of claim 1 , wherein converting the solid HEA feedstock into a powder HEA feedstock further comprises spheroidizing the powder to produce the powder HEA feedstock.
