Initial Stages of Precipitation in the Cu-Be Alloys


The clustering in Cu-Be alloys lead to large modifications of the X-ray scattering curves and to increases of both electrical resistivity and thermopower. The microstructure is investigated in the initial stages of precipitation: small clusters exist in the quenched state, but no spherical precursor precipitates are observed before the formation of plate-like G.P. zones. The evolution of the transport properties is qualitatively analyzed and the deformation effect induced by anisotropic particles is considered.
