Web1 Jan 2024 · Chapter 15 - Strain-Induced Crystallization 1. Introduction. A great variety of polymers are processed under intense flow fields (elongation, shear, or mixed)... 2. … Strain crystallization is a phenomenon in which an initially amorphous solid material undergoes a phase transformation due to the application of strain. Strain crystallization occurs in natural rubber, as well as other elastomers and polymers. The phenomenon has important effects on strength and fatigue … See more Strain crystallization occurs when the chains of molecules in a material become ordered during deformation activities in some polymers and elastomers. The three primary factors that affect strain crystallization are … See more The mechanical properties of materials are greatly affected by the orientation of the crystals in their micro-structure. The process of strain crystallization directly affects the micro-structure of the material by adding crystalline structures. Strain crystallization's … See more There are various techniques for measuring crystallization in rubber, including: x-ray diffraction, specific heat changes, and See more • Crystallization of polymers Some polymers that strain crystallize • Polyethylene • Polyethylene Terephthalate See more scroll bar hide windows 10
