Abstract:

Based on characterization of Ti-7Al using High Energy Diffraction Microscopy HEDMat the Cornell High Energy Synchrotron Source, new information was obtained on a temperature- dependent anisotropic thermal expansion, b evolution of micro-mechanical state at the grain scale under cyclic loading, c sensitivity of results from far field-HEDM to analysis variables and d evaluation of RVE size with respect to micromechanics and crystallographic texture.
