Application of Synchrotron Radiation to Investigate Deformation Behavior of Sintered Fe0-Cr/TiN Composites

摘要

Elastic deformation behavior of each phase on composite material was estimated by using a synchrotron radiation. We can obtain the arbitrary wavelength beam with a Si (111) mono-crystal monochromator. The X-ray diffraction patterns were collected during a theta-2theta scan. It was found that we could obtain the phase stress of a Fe-Cr/TiN composite material using X-ray diffraction with synchrotron radiation. Phase stresses were determined from phase X-ray elastic constant (PXEC). The hardening rate of the Fe-Cr matrix phase was controlled by TiN reinforced particle. Measured results agreed with the micromechanics model.
