Highly oriented samples of HDPE and Nylon 6, deformed in plane strain compression acquire, a quasisingle crystalline (QSC) texture. Such QSC material has been used in simple shear experiments to study the kinetics of plastic flow by chain slip. The activation parameters determined from strain rate change experiments have been interpreted in the context of thermally activated motion of screw dislocations in these QSC materials with long range coherence. This long range coherence has been established through recent WAXS, SAXS and atomic force microscopy studies having molecular level resolution.
