Abstract
We report the production of full strength compacts of metallic glass by warm extrusion of powders at the supercooled liquid state just above the glass transition temperature. The alloy used was Zr65Al10Ni 10Cu15 (at. %) which has the lowest viscosity among Zr-based metallic glasses with large supercooled liquid region. The tensile strength and Young's modulus of the glassy powder compacts were 1520 MPa and 80 GPa, respectively, which are similar to that obtained in the as-cast bulk alloy and melt-spun ribbon. This opens up possibilities of producing high strength amorphous alloys with complex shapes.
