Beaudoin, Armand J. Obstalecki, Mark 2011-08-25T22:19:39Z 2011-08-25T22:19:39Z 2011-08-25T22:19:39Z 2011-08 An experiment utilizing synchrotron radiation to measure lattice strain components from an aluminum-lithium sample during tensile loading is presented in detail. The conical slit system at Argonne National Laboratory’s Advanced Photon Source is utilized to isolate a single grain with an orientation of interest from the highly textured alloy. A total of 39 reflections contribute to the calculation of the strain tensor for each load step. Trends were realized in all six independent components of stain, and reveal an elevated initial triaxiality which approached the expected value for tensile loading of an isotropic material as the sample was loaded. Potential error sources are discussed in relation to strain measurements and considerations when using the conical slit system are presented.
