Abstract In this work, the oriented α- and β-crystals were simultaneously fabricated in the iPP parts with a β-nucleating agent by means of the oscillation shear injection molding (OSIM) technique. The β-nucleated iPP parts demonstrated an interesting deformation behavior, traced by in situ synchrotron X-ray diffraction equipped with a uniaxial tensile apparatus. In the small strain region (6.7%) from the yield point to the strain hardening point, dramatic changes in terms of the crystal… CONTINUE READING
