Abstract

PURPOSE: To start a quenching treatment of precipitation hardening type alloy near the lower limit of solid-solution temperature region in order to lower the prcipitation rate if precipitates after cooling, and to facilitate succeeding control of stress and temperature before the next aging treatment, thereafter to ensure preceiptation of anisotropic precipitates.
CONSTITUTION: An Al-3% Cu alloy single crystal is quenched from solid-solution temperature (480, 520 and 560°C) into ice-water. It is left at room temperature for a specified time (0, 10, 60 min) then its (001) axis is loaded with a 4.08kg/mm2 compressive pressure, and is subject to aging treatment in a 150°C oil bath for 5 seconds. The figure shows the anisotropy of precipitates due to stress load aging, indicating that the precipitate is isotropic at a strength ratio of 1, and the higher the strength ratio, the more anisotropy is given. That is, as the quenching temperature gets lower, more of plate-shaped precipitates appears on the (001) face perpendicular to the compressed axis. Accordingly, the process provides a means to produce precipitation hardening type alloys having various properties peculiar to anisotropy precipitated.
