Abstract :
[en] This powerpoint presentation was used as teaching material in a seminar given as part of the course “Ingénierie des matériaux métalliques”. Following on a general introduction to additive manufacturing of metallic materials, it outlines some important current issues in the development of additive technologies, by reporting on two case studies into the processing (1) of a single material system (i.e. Ti alloy Ti-6Al-4V) and (2) of a multimaterial system (i.e. a metal matrix composite). The first case study on Ti-6Al-4V reviews issues related to the dimensional accuracy of the produced components, as well as the control of their microstructures and usage properties. The second case study provides an introduction to metal matrix composites with a particular attention for the process known as laser cladding, focusing on the relationships between the thermal history during the production of a composite coating, and the resulting microstructure and properties, with special attention to the dissolution of ceramic particles (e.g. carbides) and to interfacial reactions taking place between the particles and the metallic matrix.
