Insights into High‐Temperature Uniaxial Compression
We report on strain‐rate‐dependent compression deformation behavior of Ti 3 AlC 2 at 1000°C–1200°C. At 1000°C and high strain rate (10 −2 or 10 −3 s −1) Ti 3 AlC 2 deforms in a nonplastic manner. Upon increasing temperature and reducing strain rate Ti 3 AlC 2 exhibits a limited plasticity. For instance the true plastic strain at 1200°C and 10 −4 s −1 is only 3 beyond

Molecular orientation and strain-induced crystallization of vulcanized natural rubber during uniaxial deformation were studied via in situ synchrotron wide-angle X-ray diffraction (WAXD). The high intensity of synchrotron X-rays and new image analysis methods made it possible to estimate mass fractions of the strain-induced crystals and the amorphous chains in both oriented and unoriented
