Webtant stress or strain-induced crystallization (SIC) (1). For example, SIC occurs during processing of monofilaments, oriented films or various shaped prod- ucts during mold filling. Hence, ever since this phenomenon was discovered in 1805 (2), the elucidation of its crystal morphology, kinetics and properties has WebApr 29, 2024 · For ε < 0.5, stress increases rapidly with the deformation. For 0.5 < ε ≤ 9.0, a gentle increase in the stress is observed. When strained beyond ε = 9.0, stress increases sharply again. Bond dissociation in the system initiates at ε = 14.0. This represents the material failure in the system. WebAt high flow strength, a flow-induced crystallization (FIC) occurred, producing a semicrystalline material possessing a high degree of crystallinity and primarily a monoclinic lattice structure. This FIC phase formed at a temperature (450 K) high above the quiescent melting point (≈400 K) and remained stable after cessation of flow for ... hua kuang 江南大学
