Design for Lifetime Performance

3 Units

The roles of processing and properties of a material on its performance, cost, maintenance, degradation and end-of-life treatment. Corrosion and oxidation, hydrogen and transformation-induced degradation mechanisms. Defects from prior processing. New defects generated during use/operation, e.g. generated from radiation, stress, heat etc. Accumulation and growth of defects during use/operation; crack nucleation, propagation, failure. Impact, abrasion, wear, corrosion/oxidation/reduction, stress-corrosion, fatigue, fretting, creep. Evaluation of degradation: Non-destructive versus destructive methods, estimation of remaining lifetime. Mitigation of degradation mechanisms. Statistical tools for assessing a material's lifetime performance. Capstone design project. Prereq: EMSE 372 . Coreq: EMSE 319 .
