Abstract
The application of external stress during ageing induces the oriented formation of disc-shaped aggregates consisting of rod-shaped Ag precipitates and a Cu matrix on {100} planes in single crystals of a Cu–5.7 wt% Ag alloy. Tensile stress along the [001] axis induces preferential formation of the aggregates perpendicular to the [001] axis and compressive stress induces the same parallel to the stress axis. The stress-orienting effect is determined during the initial stage of precipitation, when the formation of the aggregates starts on dislocations. The experimental result can be understood if the misfit strain of the aggregates in a direction perpendicular to the disc plane is larger than that in the parallel direction. This idea is supported by length-change measurements during ageing.
