Flow Stress of 6061 AL Alloy Composites

The relationship of flow stress to the interparticle path of two phase alloy systems is discussed and the similarity of two phase alloy systems to wire or fiber reinforced composites is described. Experiments were performed on iron wire reinforced 6061 aluminum alloys which show that the flow stress in these systems can be expressed by a similar relationship as documented for two phase alloy systems, namely, σ_flow = C₁ log λ + C₂, where C₁ and C₂ are constants, σ_flow is the flow stress, and λ is the interwire spacing within 4, 6, and 8 wire aluminum alloy composites.
