Mechanical alloying (MA) of ZrO2-8mol%ZrN system is exmained. XRD peaks from the mixed powders in ZrO2-8mol%ZrN consist of m-ZrO2 and ZrN with NaCl strucrure. After MA for 80h of the powders, the peak intensity from m-ZrO2 and ZrN was reduced and new peaks appeared. The new peaks can be indexed to be cubic fluorite structure or pseudofluorite structure. Nitrogen must be in solution during mechanical alloying, and a high-temperature form of ZrO2 is stabilized.
