Effect of route BC-ECAP on microstructural evolution and

In this study, the microstructure, tensile properties, and the fracture behavior of hypereutectic A390 aluminum alloy produced by route BC of equal channel angular pressing (ECAP) were investigated. Evolution of the rheological and microstructural We deformed samples to high enough strains that a steady state microstructures were achieved, which allowed us to investigate the evolution of both the rheological and microstructural properties. The stress exponent of n5.0 and the grain size exponent of p0 determined by fitting the strain rate, stress, and grain size data indicate that

Microstructural Evolution and Domain Structures of Flux

Barium titanate is one of the most commonly utilized dielectric materials for commercial applications. As devices continue to scale smaller, it is necessary to find processing routes that allow for the integration of high-permittivity barium titanate into the thin film geometry. In the bulk, high permittivity barium titanate can be produced at high processing temperatures (>1250°C). Microstructural Evolution and Functional Properties of Fe Mar 23, 2016 · Microstructural evolution upon processing is strongly affected by thermal gradients and solidification velocity and, thus, by processing parameters and the actual specimen geometry. By single-step solutionizing heat treatment pronounced grain growth is initiated leading to microstructures showing good reversibility.Microstructural evolution and mechanical properties of Microstructural evolution and mechanical properties of CuAl alloys subjected to equal channel angular pressing S. Qua, X.H. the cross-section geometry is unchanged after pressing, microstructural evolution of metals with high or medium SFE,
