摘要：
Stainless steel web reinforced AZ91 alloy were fabricated by melt infiltration casting method. The mechanical properties of the resultant composites were much improved in regarding to the elastic modulus, 0.2% offset yield strength, ultimate compressive strength and the strains compared to the unreinforced counterpart. The interaction between the web and the dislocations in the matrix and the load transfer from the matrix to the reinforcement are the strengthening factors. While the wire being broken, bended and pulled out of the matrix, especially the activation of much more slip bands in the matrix, suggest that both the load transfer mechanism and the dislocations proliferation mechanism contribute to the plasticity of the composites.
