摘要: At low temperatures, ionic solids of the rock‐salt structure deform by planar {110} slip and are brittle; at higher temperatures can occur on any plane zone fully ductile behavior is observed. The effect alloying this pattern has been studied for KCl‐KBr system. Pure polycrystalline KCl a 0.6% KBr alloy shown to be above 250°C, but 1.3% polycrystal remains brittle up 350°C. Associated with brittleness persistence much temperatures. More concentrated additions suppress wavy glide in single crystals approaching melting point alloys. Data presented demonstrate yield strength, work‐hardening rate, fracture stress two dilute Small solute appear influence more than increase both signific...
