Workshop 1

Diffraction Studies of Structural and Mechanical Properties

Tue. May 6, all day
A1100

Organizers: Dean Haeffner (XOR APS), Wenjun Liu (XOR APS), Ersan Ustundag (Iowa State University/Ames Laboratory)

To agenda > Updated 4/10/2008


Diffraction measurements of structural and mechanical properties provide important information for materials scientists. A wide variety of materials (metals, composites, ceramics, polymers, and biomaterials) have been the subject of such studies at the APS, and the interest in this area is growing rapidly. To survey the current research and examine future possibilities for experiments on this topic, the workshop will have four sessions with the following themes:  1) diffraction studies of grain-averaged mechanical properties (strain/stress/texture) in polycrystalline aggregates, 2) studies of individual grains using 3-D x-ray diffraction microscopy, 3) emerging areas for studying mechanical properties of materials with diffraction (including biomechanical and nanomechanical materials), and 4) theory, modeling, and analysis software associated with measurements of the mechanical properties of materials.
