From page 25...
... Three presentations addressed current computation methods directed at process modeling for consolidation and aciclitive processes and nanostructural modeling advances of the material structure at the atomistic through macro levels. Thomas Gates of NASA Langley Research Center presented a talk entitled "Computational Materials at NASA Langley: Nano-structurec!

... The ability to image the plume provides information such as plume alignment; changes in the spray pattern because of changes in the spray parameters; particle velocity, temperature, and size distributions without having to scan the plume; and powder feed-rate fluctuations (the relatively rapid frame rate can resolve fluctuations of 10 Hz or less)

From page 27...
... To apply the model accurately, one must conduct mechanical tests on bulk specimens at temperatures and grain sizes of interest. One needs to know the values of the model parameters, such as creep and diffusion constants (obtainable by curve-fitting, guessing, and/or experimentation)
