"The critical resolved shear stress of metal single crystals is generally considered to be markedly sensitive to trace amounts of impurities, and to the detailed procedures of growing, handling, and testing specimens. Wide scatter is observed for apparently similar specimens. As a result it is difficult to find reliable data in the literature for the CRSS of pure metals and, in particular, the temperature dependence of the CRSS. The CRSS of aluminium has been examined extensively by Lucke and Buhler (1963) as a function of temperature and strain rate. They obtained highly consistent values for the CRSS, and determined its temperature dependence over the range 300 to 900 °K. The purpose of the present investigation of the CRSS of lead was to determine whether reliable and reproducible data of the CRSS could be obtained. If this could be clone, then the temperature dependence would be determined and the high-temperature deformation process analyzed in a manner similar to that of Lucke and Buhler. In addition, the effect of orientation, impurity level, solute hardening, and prior deformation on the CRSS would be determined. From these data the minimum value of the CRSS could be compared to that of copper […]"--Introd., p. 1189, 1190. gccst Metals gccst Physics Canada. Natural Resources Canada. Canada.
