Microstructure-strength relationship of a deformation-processed aluminum-magnesium composite
type: CreativeWork
description: The Al-Mg composite was deformation processed by extrusion, swaging and wire drawing. Two compositions, Al-13vol%Mg and Al-20vol%Mg were used to compare the influence of second phase content. The microstructure of the composites was convoluted, ribbon-shaped second phase Mg filaments in Al matrix, which resulted from plan strain mode of Mg filaments. The strength of the material increased with the increasing of deformation ratio. Hall-Petch model and Embury's deformation processing model can be used to predict the strength of the material. The combination of high strength and high conductivity of the composite made it a promising structure material in various industries.
