Reduced Oxygen Nanocrystalline materials show Improved Performance

Scientists at UConn and North Carolina State University have found that reducing oxygen content in some nanocrystalline materials may improve their grain size stability at elevated temperatures. This graphic shows the pattern of stability for Iron-Chromium-Hafnium nanograins with oxygen (represented by red triangles) and without oxygen (represented by black squares) as temperature increases relative to thermodynamic prediction.
