Grain size stability and hardness in nanocrystalline Cu-Al-Zr and Cu-Al-Y alloys

Cryogenic high energy ball milling has been used to synthesize nanocrystalline Cu-14Al, Cu-12Al-2Zr and Cu-12Al-2Y alloys by mechanical alloying. The alloys were studied with the aim of comparing the effect of substituting Y and Zr in place of Al, in Cu-Al alloys, on the grain size stability at elev...
