Abstract
The deformation behavior of a powder-metallurgy processed Zr65Al10Ni10Cu15 metallic glass was characterized in the supercooled liquid region under a condition where crystallization is controlled to occur during deformation. The alloy exhibited a tensile elongation as large as 750% at 6.3 x 10(-3) s(-1)-696 K though crystallization occurred during deformation.
