Abstract

Some unusual contrast effects have been observed in β-brass. Double images of ½ screw dislocations appear when g · b=0 and the double images of edge dislocations which occur under the same conditions are more intense and less sensitive to orientation changes than would be expected. These and some unusual dotted contrast effects are believed to be due to the high degree of elastic anisotropy of β-brass.
