Strain induced recrystallization

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. ... including flow-induced phenomena, over wide ranges of strain rates for a series of unentangled and entangled polymeric liquids during the last few ... Web11 Apr 2024 · The recrystallization behavior caused by strain-induced grain boundary migration is more likely to occur. Similarly, the disappearance of KBs caused by the dissolution of LPSO makes the energy originally consumed by KBs more effective in promoting DRX behavior.

WebThe origin of lattice strain and the mechanism of strain-induced instability are revealed. We anticipate that the successful identification and solving of strain-induced degradation represent a direction to improve the intrinsic stability of OIHP solar cells. ... In situ transformation vs dissolution–crystallization. Chem. Mater. 26, 6705 ... WebStrain-induced crystallization (SIC) of rubber is a self-reinforcing mechanism of rubber. The phenomenon was found in 1925, however, the elucidation of it has been a controversial topic since then. In 2002, synchrotron X-ray made it possible to measure stress-strain relation and SIC simultaneously. In 2012, the time constant of SIC is revealed ... WebRecrystallization is a thermally activated process, con- sisting of the generation of strain-free grains and their growth at the expense of the deformed grains until the deform grain is entirely consumed [28]. And the driving force for recrystallization is the energy stored in the ma- terial during deformation [33]. The purpose of recrystal- red ar-15 accessories amazon

To explain this resistance, the literature. often mentions the phenomenon of strain-induced crystallization which takes place at fatigue.

WebRather than the shear rate as the driving force, a viscoelastic approach is proposed here, where the resulting recoverable strain (expressed by the elastic finger tensor) with the highest relaxation time is the driving force for flow-induced crystallization. Thus we focus on the polymer that experiences the flow, rather than on the flow itself. WebThis method is called strain-induced crystallization. It occurs when polymers are stretched beyond its yield point. One usually observes a noticeable increase in modulus due to the formation of crystals that act as a physical reinforcements similar to fillers. Thus when strain induced crystallization occurs, the stress increases as well.
