✦ Synopsis

The aging at room temperature of a nanocrystalline equiatomic ZnSe alloy produced by mechanical alloying was investigated using X-ray diffraction (XRD) and differential scanning calorimetry (DSC) techniques. The measured XRD patterns showed the presence of the peaks corresponding to the crystalline trigonal selenium (c-Se) phase. It is observed that the ZnSe phase is stable with aging. The appearance of the c-Se phase is attributed to the migration of Se atoms located at the interfacial component of the as-milled ZnSe nanostructure with aging.

Alloying of Ga with Se is observed in elemental Ga:Se ΒΌ 50:50 mixture upon high-energy ball milling. X-ray diffraction of samples milled in the 1=2 , t , 3 h range displays evidence of hexagonal gallium selenide (GaSe). At longer milling times t . 10 h two wide bands are superimposed on the crystall
