Book Description
The microstructure and aging behavior of a centrifugally cast A356 Al-SiCp metal matrix composite was studied as a function of post-fabrication processing via transmission electron microscopy (TEM) and differential scanning caloritemetry (DSO). The effects of total rolling strain, strain per rolling pass and rolling temperature on both microstructure and precipitation behavior were investigated. It was found that post fabrication processing had relatively little effect on the kinetics of the various precipitation processes that constitute aging, although they affected the amounts of the various precipitates significantly.

Book Description
Discontinuous reinforced aluminum (DRA) composites are attractive as structural materials because of their desirable stiffness and strength to weight ratios and relative ease of manufacture. However, they typically display low tensile ductility and fracture toughness. In this work, the impact of post- fabrication deformation processing and heat treatment on the fracture properties of a 17.5 vol. % SiCsubp reinforced Al 6092 matrix composite is investigated. Process temperature, total strain and strain rate during extrusion were varied in order to explore the feasibility of obtaining Particle Stimulated Nucleation (PSN) of recrystallization during processing, with the goal of refining the matrix grain size. Additionally, various combinations of solution and aging treatments were investigated with the aim of obtaining a number of stable matrix microstructural conditions with varying levels of composite strength and fracture toughness. A preliminary investigation of fracture mechanisms and their dependence on the matrix aging state has also been carried out using optical and scanning electron microscopy (SEM) and differential scanning calorimetry (DSC), and is reported here.

Book Description
Differential scanning calorimetry was conducted using centrifugally cast monolithic A356 aluminum material and 26 volume percent silicon carbide (SiC) particle reinforced A356 aluminum matrix composite material in as-cast, cast and rolled, and cast and extruded conditions. Electrical resistivity and matrix micro-hardness measurements during isothermal aging treatments were also conducted. the effects of thermomechanical processing and SiC particle additions on the mechanical properties and aging kinetics of the metastable phases in each material were studied.
