Abstract

A large sized La₆₂Al_15.7(Cu, Ni)_22.3 amorphous alloy was produced by spray deposition, and its compressive deformation behavior in supercooled region was investigated. It is found that both the strain rate and test temperature significantly affect the stress–strain behavior of the amorphous alloy in the supercooled liquid region. The deformation behavior is characterized by a transformation from unsteady–state flow to steady–state flow with the decrease of strain rate or increase of heating temperature in the supercooled region. After hot extrusion at 443 K, the alloy is still amorphous and its density (5.924 g/cm³) is 96.6% of the suction-cast amorphous alloy with the same component (6.134 g/cm³) when the reduction ratio, strain rate and heating temperature are adopted as 6.25, 5×10⁻³ s⁻¹ and 443 K, respectively.

Key words: spray deposition La–based amorphous alloy hot extruding plastic deformation supercooled liquid region
