摘要：

The kinetics of mechanical alloying (MA) by planetary ball milling in CuAl are studied. MA in CuAl takes place by continuous diffusive intermixing at an appreciable rate only after the grain size is reduced to a level below 100 nm. Furthermore, the sandwich lamellar structure, that arises in the early stage of MA, is conductive for the said mechanism of intermixing.
