INFLUENCE OF REINFORCEMENT CONTENT ON TENSILE RESPONSE AND FRACTURE BEHAVIOR OF AN ALUMINUM ALLOY METAL MATRIX COMPOSITE

摘要

In this paper, the results of a study that examined the intrinsic influence of ceramic particulate reinforcements on tensile deformation and fracture behavior of aluminum alloy 2014 is presented and discussed. The candidate aluminum alloy was reinforced with two volume fractions of the alumina (Al_2O_3) particulates. Influence of particulate reinforcement on microstructural development is highlighted. Samples of the aluminum alloy-based metal matrix composite were deformed in uniaxial tension. The influence of nature of loading and intrinsic microstructural effects on stress versus strain response, mechanical properties, deformation and final fracture behavior are neatly elaborated and discussed in light of intrinsic microstructural effects, deformation characteristics of the microstructural constituents and nature of loading.
