Lecture: High temperature behaviuor of metallic materials and their energy and industrial applications

prof. Riccardo Donnini


High temperature issues in energy and industrial applications and the role of the metallic materials. Creep, stress relaxation, low and high cycle fatigue, thermo-mechanical fatigue, fracture mechanics: description, intepretation and practical aspects. High temperature plastic deformation: the microstructural phenomena and their effects on the manufacturing processes. Mechanical testing at high temperature: experimental procedures and standards for creep test, stress relaxation test, fatigue test, thermo-machanical test. Constitutive equations of metalic materials at high temperature: description and intepretation. Remarks on principal metallic alloys and their performances at high temperature. High performance metallic alloys: nickel based superalloys, high alloy steels, metal matrix composites.
