Dislocations in Solids

Bacon and Osetsky present an atomistic model of dislocation-particle interactions in metal systems, including irradiated materials. This work is important in anticipating the behavior of dislocation motion. New mechanisms for dislocation, generation under shock, loading is presented by Meyers et al. These models provide a basis for the understanding of shocked material. Saada and Dirras provide a new perspective on the Hall-Petch relation, with particular emphasis on nanocrystals. Of particular significance, is the square-root of grain size relation are explained. Robertson et al. Gives the model a broad range of properties.

• Flow stress of metal systems with particle hardening, including radiation effects







• New model for dislocation kinetics under shock loading









• Explanation of the effects of nanoscale grain size on strength









• Mechanism of hydrogen embrittlement in metal alloys ~
