Tensile Properties of NaCl-BaNr Solid Solution Single Crystals

Abstract

Single crystals of NaCl-NaBr alloys to 10-mole % NaBr were tested in tension. Crystals to 1-mole % NaBr were ductile but no ductility was observed with 5- and 10-mole % NaBr crystals. Addition of 0.5-mole % NaBr appeared to cause softening, perhaps due to a scavenging effect. Microhardness showed a continuous increase with NaBr to 10 mole %, perhaps due to clustering of the solute atoms. Crystals tested in methyl alcohol had lower yield stresses and were more ductile.
