Paper Title:
Microstructure and Mechanical Properties of Al-Mg-Sc Alloy Processed by Semi-Solid Continuous Casting-Extrusion
  Abstract

High tensile strength Al-3Mg-0.5Sc alloy wires can be produced by a method called semi-solid continuous casting-extrusion and on-line solution process (CCES). The effects of artificial aging and the combination of the artificial aging and cold drawing on the microstructures and properties of alloy wires were respectively investigated. TEM observations reveal that a large number of dislocations and Al3Sc particles distributed in the Al-matrix of Al-3Mg-0.5Sc alloy produced by semi-solid CCES.After directly artificial aging (DAA), the tensile strength is 353MPa and elongation is 19.9%; After cold drawing following artificial aging (CDAA), the tensile strength is 378MPa and elongation is 17.7%; After artificial aging following cold drawing (AACD), the tensile strength is 435MPa and elongation is 10.4%.
