Production of AA2124/MoSi<sub>2</sub>/25p composites and effect of heat treatment on their microstructure, hardness and compression properties

Abstract: AA2124/25vol%MoSi 2 composites were processed by two powder metallurgy routes: high energy ball milling of the reinforcement and alloy powder (B composite) and wet blending with cyclohexane (W composite), both followed by extrusion to achieve full consolidation. As-extruded and heat treated composite bars were studied microstructurally and mechanically (hardness and compression tests under quasistatic loading). Microstructure and fracture profiles were observed by scanning electron microscopy and the reaction … Show more

“…Some challenges faced during the heat treatment of MoSi 2containing composites are the formation of undesirable phases or excessive oxidation of MoSi 2 that may deteriorate the composites' integrity and properties. Accordingly, some authors have focused on process temperature, residence time, and atmosphere as critical heat treatment parameters (Zeng et al, 2002;Zamani et al, 2012;Niu et al, 2013;Abdollah-Pour et al, 2014).…”
