説明

<jats:p>Amorphous Zr65.0Al7.5Cu17.5Ni10.0 powder has been prepared by mechanical alloying from crystalline elemental powders. The powders are characterized by x-ray diffraction and differential scanning calorimetry (DSC). The amorphous phase forms after about 50 h of milling, and exhibits a wide supercooled liquid region of up to 87 K before crystallization. The transformation to the crystalline state and the melting behavior of the crystalline alloy have been followed by isothermal and constant-rate heating DSC. The results are compared with data for melt-spun and water-quenched amorphous material.</jats:p>
