Investigation of the Microstructure and Mechanical Characteristics of an Al-Based Bimetallic Composite Reinforced with Steel Grid

Abstract

The microstructure and mechanical properties of an Al-based metallic composite reinforced with a steel grid are investigated. The process used to produce such a bimetallic composite consists in combining high pressure and high temperature ensuring the diffusion of active alloying elements. It is shown that the size of the stacked steel grid has a significant effect on the mechanical characteristics of the composites. The aluminum-based composite reinforced with a finer steel grid has higher mechanical properties compared to the composite with a coarse grid, due to the more homogeneous joining of the Al sheets.
