SOME EXPERIMENTS ON THE RELATIVE HARDNESS OF GRAINS AND GRAIN BOUNDARIES IN THE PRESENCE OF SOLUTES.
Abstract
An alloy of zone refined aluminum plus 0.0124 atomic percent copper has been used to test the possibility that the broad bands of grain boundary hardening due to solute segregation found by Westbrook and Aust (1963) in their tin-silver-, and gold doped zone-refined lead represent a general phenomenon. The results revealed no hardening effect at the boundaries of the copper-doped aluminum. In view of the fact that these results are in striking contrast to those found by Westbrook and Aust, many of the experimental techniques used and the results themselves are described in greater detail than might otherwise be warranted for negative results.
