Poster presented at The Search for a Sustainable Energy Future: Challenges for Basic Research, A Mini-Symposium sponsored by the Energy Working Group at Penn, March 9, 2007.

Abstract

The research involves experiments on model lab heats of an ultra-high-strength steel (high C, low Ni ) and a high-toughness, high-strength steel (high Ni, low C) to determine the limits of toughness as a function of yield strength, grain-boundary purity, and hydrogen fugacity. In addition, the existence and mechanism of brittle intergranular cracking in ideally pure steels is being investigated.
