Point Defects and Dislocations in Silver Chloride temperature, and purity establish that the dislocations are pinned by divalent impurities which migrate with an activation energy of 0.46 eV. (b) Observations of ionic conductivity during pulsed plasticity indicate that excess silver interstitials are created with an efficiency of 10. fractional co

Dislocations in Spinels and Related Structuresin corundum. The central stacking fault has a lower energy than the other two and will therefore be much wider. Recently, very thin platelets of BaFe.O. were obtained and examined with the electron microscope. The lattice of this compound is very similar to that of spinel. Evidence was obtained of d

Dislocation Multiplication information concerning multiplication processes to a better understanding of yielding, strain hardening, and fracture is emphasized. Experimental observations on the growth of slip bands in magnesium oxide and lithium fluoride by transmission electron microscopy and optical etch-pit techniques have

The Surface-Sensitive Mechanical Behavior of Ionic Crystalsace contaminants, and surface defects. These three factors, the extreme notch sensitivity of ionic crystals, and the results of some recent investigations performed mainly on NaCl, LiF, and MgO crystals are discussed in connection with Roscoe, Rebinder, and Joffé phenomena.

The Dislocation as a Fundamental New Concept in Continuum Mechanics can be delineated today. The theory of the residual stress state is rather well-developed. The state is described geometrically by elastic strain and lattice curvature, the latter being equivalent to the dislocation density. The static description uses force and couple stresses, the latter being th
