Notes:
A nanostructured aluminium alloy powder, prepared by rapid solidification via gasatomization, was consolidated into bulk material under various processing conditions via hotextrusion. The microstructure modifications and mechanical properties of the consolidated alloys asa function of the extrusion conditions were investigated. The increase in the extrusion-load with theincrease of extrusion-rate and decrease of temperature are shown and discussed in association withthe modification in the microstructures. The differences in mechanical properties measured bycompressive tests are also discussed in association with the extrusion parameters. Furthermore,suggestions are given for rationalising the extrusion ratio and temperature conditions for theconsolidation of nanostructured aluminium alloy powders via hot extrusion
