HEAT TREATMENT EFFECTS ON SOME PHYSICAL PROPERTIES OF METALLIC SINGLE CRYSTALS.
Abstract
Results on the effect of plastic deformation on the electrical resistivity of high purity polycrystalline copper, aluminum and nickel showed the change in electrical resistivity with plastic strain was not affected by strain rate over the range investigated. Extended work on nickel showed that stages 2 and 3 of plastic deformation were well defined for that metal. The results of the effect of quenching on the electrical resistivity of beta-brass showed two resistivity peaks for resistivity measurements made 3 minutes after quenching and one resistivity peak for resistivity measurements made approximately 18 hours after quenching in the relative change in resistivity versus quench temperature graphs. Results on X-ray analysis of beta-brass after quenching provided no evidence for the formation of antiphase domains or that a large amount of disorder can be quenched in. There was some evidence that stacking faults might be formed in the crystal by the quenching process. (Author)
