Abstract:

This final report summarizes work done by researchers from Iowa State University, University of Wisconsin-Madison, SRI International, and University of Vermont for this grant. The first two groups investigated candidate material systems for high-temperature aerospace applications. These investigations included theoretical, computational and experimental efforts, and focused mainly on molybdenum-silicon-boron and diboride alloy systems. These two groups also collaborated in the production of candidate test samples for evaluation in the inductively coupled plasma torch facility at the university of Vermont collaborated on the development of improved non-intrusive diagnostics aimed at providing personnel focused their efforts on making quantitative measurements of key surface reaction rates from relative laser based measurements of the reacting species gradients near the surface.
