>Dislocation loops formed by quenching thin aluminum specimens in iced brine were studied by the transmission electron microscope technique. As- quenched specimens contained loops 200 A to 600 A in diameter with a density of l0/sup 15/ loops per cubic centimeter. Quenched-in loops were completely removed by heating to 200 deg C for ten minutes or by cold rolling to a 5% reduction in thickness. The disappearance of the loops was accompanied by an increase in the number of irregular kinked dislocation lines. (auth)
