COLD WORK AND THE DUCTILE-BRITTLE TRANSITION OF SILVER CHLORIDE

Abstract

Polycrystalline silver chloride specimens having different microstructures were prepared by ex truding monocrystals or precompressed powder at varying temperatures. Extrusion at high tempera ture (370 C) produced a fully recrystallized equiaxed material which was brittle and fractured by simple cleavage below its transition tempera ture (60 C for notched specimens). Extrusion at low temperatures (down to -196 C) produced an extremely tough cold worked material with grains elongated in the extrusion direction. This mate rial fractured below its transition temperature (which varied from -20 C to -200 C) by an inter granular mode.
