Effect of precipitate particles on creep of aluminum-copper alloys during age hardening

Sep 1958

Spherical or platelike precipitates were prepared in aluminum alloys with 1 to 4 weight percent copper. The effects of controlled sizes and distributions of particles were determined by creep, tensile, and hardness measurements, by quantitative metallographic evaluation of the particle characteristics, and by X-ray and electron-microscope examinations.
