Transition from five-fold symmetric to twinned fcc gold particles by thermally induced growth
Article Abstract:
Research was conducted to examine the transition from five-fold symmetric to twinned FCC gold particles by thermally induced growth. The objective is to study the details of any structural rearrangement that may arise during thermal treatment of highly dispersed metal particles in a preceramic inorganic matrix using in situ X-ray diffraction method. Results indicate that accurate X-ray data and simulations using the Debye functions can provide valuable insight into the complex process of crystal growth for nanocrystals.

Investigation of real-time microstructure evolution in steep thermal gradients using in-situ spatially resolved X-ray diffraction: a case study for Ti fusion welds
Article Abstract:
Research was conducted to examine Ti fusion welds. A spatially resolved X-ray diffraction method using intense synchrotron radiation was developed and refined to generate microstructural and phase information down to 200 microns in spatial extent in materials subjected to steep thermal gradients during processing. Results indicate that the phase transitions yield two distinct microstructural regions, namely, a fusion zone and a heat-affected zone during the welding process.
