Three-Dimensional Materials Science at Sandia National Laboratories: Leveraging Experiments, Characterization & Models


Jonathan Madison
Sandia National Laboratories

This talk will highlight a variety of capabilities at Sandia National Laboratories focused on the investigation of material performance with an emphasis on three-dimensional characterization. Additionally, a few specific examples will be shown highlighting the benefits of sharing such characterization between experiments and models. One set of examples will focus on processing defects in laser-welds and the development of predictive tools to ascertain the impact of such defects on mechanical performance. A second set of examples will center on kinetic monte-carlo microstructural evolution models. These models have been developed to offer a first approximation of grain structure in the vicinity of a moving heat source with direct application to additive manufacturing. A third set of examples will demonstrate how full-field three-dimensional descriptions of “non-traditional” formations can aid scientists in making larger-scale design and engineering decisions.
