Abstract
The plastic properties of extended aluminum (99.996) single crystals were investigated in the temperature range 77° to 353°K. Both the critical resolved shear stress and coefficient of shear hardening were found to increase with a decrease in temperature, and were consistent with the Schmid law of critical shear stress governing the initiation of the slip process. Measurements were also made on the density of slip bands, which was found to increase with decreasing temperature in a manner similar to the shear hardening coefficient. Some observations were made on the appearance of slip bands on etched and unetched electrolytically polished surfaces, and on the general complexity of the slip process.
