Abstract

Glass formation was achieved by mechanical milling of crystalline Ni 59Ti16Zr20Sn5 pre-alloyed powders. Compared to the glassy alloy ribbon of the same composition obtained by melting-spinning method, the alloy powders milled for 24 h exhibited a lower crystallization temperature and do not have a distinct glass-transition characteristic. X-ray diffraction (XRD) and transmission electron microscopy (TEM) results indicated that a small fraction of the powder exists in nanocrystalline state within the glassy matrix. The obtained Ni 59Ti16Zr20Sn5 powdered specimen was heated rapidly by microwave radiation and the bulk porous sample was obtained under a low applied pressure of 5 MPa.
