Physical models are developed for the evolution of the dislocation density in metals subject to irradiation at elevated temperatures. Two basic processes ara shown to account for the experiment observations: the generation of dislocation line length takes place by the Bardeen-Herring mechanisms, whe
Hetzrogwzous nucleation experiments hate been carried out using xl!oy droplets concain& in a nncleant matrix. These specimens were made using a simple casting tend annealing trrstmcnt of selected alloys. Thermal anal+ was used to detect the nucleation in the alloy droplets. The results obtained show
At present no dislocation theories can answer the above question, and we suggest that a modified interpretation of K, is dispensable to account for the yielding behavior of pressurized iron. Another question is left unanswered which is about the result of coarse grained specimens. The increase of
In an article by Reid U) dislocation mobilities and energies were evaluated for the b.c.c. refractory metals and iron. The dislocations he considered were edges and screws with various Burgers vectors on the (110) and (100) slip plane. The purpose of this letter is to extend the technique to include
