Improvement of properties in Cu–Ag composites by doping induced microstructural refinement
نویسندگان
چکیده
The microstructure, precipitation kinetics, electrical conductivity, and mechanical properties of Cu-7.9 wt%Ag Cu-5.8 doped with 0.6 wt%Nb were investigated. As-cast microstructure revealed both discontinuous continuous Ag in Cu matrix. Differential scanning calorimetry data indicated that occurred at higher temperatures activation energy. Both micro-sized nano-sized Nb particles observed the Nb-doped Cu–Ag alloy. doping significantly suppressed growth precipitates consequently increased energy volume fraction precipitates. Because larger finer-spaced precipitates, alloy showed hardness strength than un-doped Cu–Ag. After cold-rolling, remained

Effects of different amounts of lead (Pb) and tin (Sn) on microstructure and tensile properties of the AZ91 alloy were studied. The results presented that the microstructure of AZ91 alloy is consisted the α-Mg phase and semi-continuous network of β-Mg17Al12 intermetallics. For the as-cast AZ91 alloy, the average grain siz and the β phase volume fraction were 96.2 µm and of 25.3%, respectively. ...
متن کاملGeometrical Mesh Improvement Properties of Delaunay Terminal Edge Refinement
The use of edge based refinement in general, and Delaunay terminal edge refinement in particular are well established for planar meshing, but largely on a heuristic basis. In this paper, we present a series of theoretical results on the geometric mesh improvement properties of these methods. The discussion is based on refining a mesh to meet a specified angle tolerance.
