Cu 40 Mg 60 amorphous alloy powders, prepared by mechanical alloying of the constituent elements, and Cu–MgO samples, made by the self-sustaining reaction between Cu 2 O and Mg in stoichiometric amounts and additional ball milling, were characterized by physical methods (DSC, XRD, and XPS). The catalytic properties of the specimens were tested in the dehydrogenation of 2-propanol and in the ...

Mechanical ball milling is a useful technique for systems with positive enthalpy of mixing. With this technique solubility of a solute in a solid solution can be enhanced. Al-Zn system has positive heat of mixing. High energy ball milling has been
