Study on Dislocation-Divalent Cations Interaction in Potassium Chloride Crystals by Strain-Rate Cycling Tests Combined with Ultrasonic Oscillation

A large number of investigations on strength of materials have been made with alkali halide crystals [1-5]. This is because the crystals are readily available and transparency. Furthermore, they have simple crystal structure such as rock salt type, compared with some metals. Therefore, alkali halide contained additives is an excellent material for an investigation of mechanical properties.
