Wear of nanostructured FeNiMnAl

Wear of nanostructured FeNiMnAl is being studied to determine how the dry sliding wear behavior and wear mechanisms of a range of recently-discovered, very high strength, nanostructured, b.c.c.-based FeNiMnAl spinodal alloys vary with changes in the microstructure (spinodal wavelength, phase composition, interphase interface coherency) produced by ageing. Testing is being performed at a range of speeds in air, inert atmosphere, and oxygen, and the results will aid in understanding the effects of local heating and of oxidation, including the role played by third bodies (wear debris) in the wear process. This work is performed in collaboration with Oak Ridge National Laboratory and the University of New South Wales.
