Abstract
A laboratory method of producing amorphous powder by fine gas jet impingement of molten Al–Mg–Zn alloy is described. The powder has been characterized by X-ray diffraction and differential thermal analysis (DTA) techniques. The grain size of the powder varied from 5 to 80 μm . The fine grains (size upto ∼20 μm) are completely amorphous. However, large grains are partly amorphous. Using the DTA technique, glassy–crystalline phase transition temperature Tg is found to be 473.6°C. Vickers hardness of the grains is in the range 215 to 255 kg/mm2.
