Abstract Scope |
Stress rupture strength and oxidation resistance are the initial screening criteria for development of alloys at high temperatures. Due to the success of environmental coatings, alloying strategies focus more on increasing high temperature mechanical strength rather than environmental resistance. However, coatings degrade over time and can expose the base material to an oxidizing environment during service. Thus, there is a growing need to understand the impact of alloying elements on both mechanical and environmental resistance. Unfortunately, this problem is fraught with complexities. Alloy components have very different affinities for oxygen, different bulk diffusivities, and oxide film growth is frequently incongruent. Further complicating matters, standard oxidation tests are low-throughput, probing one temperature and a one-material-at-a-time approach. In this talk, we will discuss a collaborative effort on developing a high-throughput oxidation test, which is able to simultaneously evaluate the oxidation behavior of multiple materials and temperatures in a single run. |
