ON THE INTERSECTION MECHANISM OF PLASTIC DEFORMATION IN ALUMINUM SINGLE CRYSTALS

摘要

A refinement of the Seeger model for intersection process is proposed which is in better agreement with experimental observations than the original. It is shown that, in single crystals, the strain hardening in Stage II is mainly due to the short range interactions when intersection is the rate controlling process. It is also demonstrated that the creep curves as predicted by this theory, without reference to any of the empirical laws of creep, are in good agreement with the observation.
