Abstract

The compressive deformation behavior of a Ce₇₀Al₁₀Cu₂₀ bulk metallic glass at room temperature and in the supercooled liquid region was investigated at strain rates from 8 × 10^-4 to 7 × 10^-2 s^-1. The material exhibited excellent mechanical formability with a high compressive strain of ∼89% at 8 × 10^-4 s^-1 and 420 K. The material could be compressed from a thickness of 1 mm to ∼106 μm. Excellent formability in the microscale was demonstrated when the sample was deformed in the supercooled liquid region. The result indicates this alloy is a promising material for fabricating microdevices.
