Superplastic flow in a Zr65Al10Ni10Cu15 metallic glass crystallized during deformation in a supercooled liquid region

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...

Zusammenfassung:	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.
