New material gives copper superalloy-like strength
Breakthrough material could transform aerospace, defense and industrial applications.
The alloy holds its shape under extreme, long-term thermal exposure and mechanical stress, resisting deformation even near its melting point, noted Patrick Cantwell, a research scientist at Lehigh University and co-author of the study. By merging the high-temperature resilience of nickel-based superalloys with copper — which is known for exceptional conductivity — the material paves the way for next-generation applications, including heat exchangers, advanced propulsion systems and thermal management solutions for cutting-edge missile and hypersonic technologies. Alum Joshua Smeltzer ’17 ’23 Ph.D., now a design engineer at Honeywell, also contributed to the research, performing advanced microstructural characterization of the superalloy using Lehigh's Atomic Resolution Microscope (ARM).
