Scientists say they have created a new method of testing materials that allows predictions to be made about their ductility, which could lead to the production of virtually “unbreakable” metals for use with components in a variety of applications.
The discovery was reported by scientists at Ames National Laboratory in cooperation with Texas A&M University.
Tests were performed on a series of predicted materials known as refractory multi-principal-element alloys, or RMPEAs. These alloys are well suited for use in high-temperature applications, including nuclear reactors, propulsion systems, and a variety of others.
“The predicted ductile metals underwent significant deformation under high stress,” Ouyang said of the team’s validation tests, “while the brittle metal cracked under similar loads, confirming the robustness of new quantum mechanical method.”
