Steels and superalloys for energy applications
One of Cei's major activities is in the optimization of manufacturing processes for improved steels and superalloys for energy applications:
-
Microstructural control for improved material performance under harsh service conditions: high temperature applications, deep sour gas wells, etc.
-
Microstructure–property relationships
-
Degradation and failure mechanisms: aging, oxidation, creep, corrosion, etc. Cyclic conditions and the overlapping of mechanisms: thermomechanical fatigue, creep-fatigue. Temperature gradients and thermal shock, wear, radiation. Mechanical properties.
-
Surface treatments (i.e. shot peening). Investigation of surface reactions and mechanisms at high temperature
-
Modeling
-
Bimetallic bonding and production of components through: thermomechanical processes, hot-pressing, HIP and high vacuum furnaces.
-
Hot isostatic pressing for powder consolidation: atomization, capsule design and manufacture, final machining. Alternative to forging plus machining.
