Methods of Fabricating Refractory Complex Concentrated Alloys
A new fabrication method yields oxidation- and corrosion-resistant alloys for aerospace, defense, and energy devices.
Researchers at Purdue University have developed a new method for fabricating refractory complex concentrated alloys (RCCAs, comprised of metals such as molybdenum, niobium, tantalum, and tungsten). These alloys have the potential for use in a myriad of advanced ultra-high-temperature components for military/defense, energy production, aerospace, and transportation applications. Current RCCAs and conventional superalloys undergo significant degradation in mechanical properties and corrosion resistance at temperatures well above 1200oC. The Purdue University approach yields RCCAs with tailorable structures and chemistries for enhanced high-temperature mechanical and chemical performance.
