Summary
Major families of high performance metallic alloys: - Stainless steels: austenitic, ferritic, martensitic, duplex for applications in corrosive environments - Nickel alloys: alloys for applications in wet environments and super alloys for applications at high temperatures and under severe mechanical loadings - Zirconium alloys: grades for chemical engineering and grades for nuclear industry - Titanium alloys: biomedical applications and weight saving of structures - Shape memory alloys: functional applications especially in medical field - Aluminium alloys: maritime et aeronautical applications Concept of multi materials: - Multiphased steels and TRIP steels: materials with composite microstructure - Composite materials: the three types of matrix (metal, polymer and ceramic) and the different expected functions of the reinforcements - Welded materials: the different welding processes, their importance in the automotive industry for weight saving - Metallic foam: a solution for structure lightening.
Educational goals
In this module, high performance materials intended for applications at high temperatures and in corrosive environments, with high mechanical strength allowing lightening of structures or exhibiting interesting functional properties are presented. Performances limitations of these materials are discussed according to their microstructures. Some elaboration processes are also discussed. The module comprises two parts. In the first part, the major families of metallic alloys, mainly designed for severe environments, are presented. Each family is described in regards with the metallurgy of the material and with its microstructure which impact is analysed on targeted performances. In a second part, the concept of multimaterial or hybride material is discussed according to the scale of the constituent of the multimaterial. The scale ranges from mesoscopic size (as for multiphased steels) up to macroscopic size (welded materials). Composite materials are largely considered.
