A High-Power, Ceramic, RF Generator and Extractor
65349 The quest for alloys capable of extended use under severe service conditions has recently prompted interest in dual-phase Cr/TaCr2 intermetallic alloys. However, their brittleness and poor fracture toughness at ambient temperature have greatly limited their applicability. To overcome these disadvantages, this project will conduct alloy design and development using a macroalloying and microalloying approach. Phase I, will fabricate and process Cr-based Laves phase alloys. The newly developed alloys will be subjected to microstructural, oxidative, and mechanical property characterization. The feasibility of the alloying approach, and the applicability and advantages of Laves-phase-based alloys as new high-temperature structural materials will be demonstrated. Commercial Applications And Other Benefits as described by awardee: The new alloys should have applicability to many advanced heat engines and energy-conversion systems to increase their thermal efficiency, to provide savings through increased component life, and to improve system reliability and performance.
