Materials+Selection+Process

Phase 1 – Eliminating factors Self welding: yes/no – except blades Machining: yes/no Larson Miller Parameter: 25 or higher for HP components

Phase 2 – Performance ranking Cost of material Oxidation Yield Strength unless we can find a critical value Fatigue? Ductility/toughness?

Phase 3 – Thermal Matching Weldability to other components
