Inhomogeneous Deformation in Compression – Comparison of Two Bulk‐Metallic Glasses
Source abstract
Abstract
The mechanical behavior of the work-hardening Cu47.5Zr47.5Al5 bulk-metallic glass in compression was investigated and compared with that of Zr55Ni5Al10Cu30 bulk-metallic glass. Two glassy alloys exhibit substantially different plastic-flow behaviors and shear-band patterns. Cu47.5Zr47.5Al5 displays much smaller inhomogeneity of the plastic deformation both in time and in space than Zr55Ni5Al10Cu30. The work-hardening capability of Cu47.5Zr47.5Al5 may originate from deformation-induced nanocrystallization that may strengthen effectively a shear band.
