Simulating the rheological behaviour of an AlMg6/10% SiC metal matrix composite under high-temperature deformation

Abstract

Abstract The study presents the verification of a structural-hierarchical model of flow stress designed to describe the rheological behaviour of metal matrix composite materials. In the study, a composite with a matrix based on the AMg6 alloy reinforced with 10% silicon carbide is a model material. The model has been verified by experimental data obtained at a deformation temperature of 400 °C for strain rates ranging from 0.1 to 5 s-1. The identification results have shown that the model can be used to describe the rheological behaviour of metal matrix composites based on the AMg6 alloy under high-temperature plastic deformation.
