Fundamentals of Science and Technologies of Metallic Materials

Educational goals

The course deals with issues related to the materials used in new production technologies and the effects they have on their properties. Describes the main materials used today in these applications, to provide useful knowledge in the design, choice of materials, implementation and performance verification according to the latest regulations. With particular reference to the metallic materials, the phenomena induced by the production technologies that alter the microstructure are treated, conferring peculiar characteristics that modify the mechanical and operating behavior compared to the materials produced with traditional cycles. The main surface and thermal treatments adopted after the production process are identified.

Course content

1. Materials science and engineering in the forthcoming industry
2. Base concepts of materials science and advanced technology (materials classification, properties, materials design for products, criteria of selection)
3. 3D printed materials
a. Standardization, qualification and certification of materials
b. Fields of application, from materials standards to products qualification
c. Feedstock characterization (powders, wires, etc.)
d. Traditional materials vs 3d printed (SLM, SLS, DED,FDM,MIM)
4. Materials
a. Metals (Nickel alloys, titanium alloys, aluminum alloys, stainless steels, CoCr alloys)
b. Polymers (plastics for filaments and powders i.e. PLA, ABS, photopolymers.)
c. Ceramics and cements
d. Composites
i. Base concepts of non-stationary solidification of metals
ii. Microstructure and correlation with mechanical properties, anisotropy
iii. Post processing heat treatments and surface treatments
iv. Corrosion of 3D printed metallic alloys
5. Shape memory alloys and applications to 4D printing

Teaching methods

Lectures with slide projection and laboratory activities in groups defined on the basis of the number of students. The lab activities will be devoted to the execution of tests and measurements according to international regulations on the materials studied during the course. The students will be involved in the use of machines and equipment available at the University Service Center - Engineering Laboratories.

Assessment and Evaluation

Oral examination concerning the topics covered during the lectures. Discussion of results obtained during the laboratory activities – presented by students in form of report - will be done at the beginning of the oral examination. The discussion will cover aspects related to the mechanical characterization or the durability assessment materials

Further information

If the teaching activity would be held in mixed mode or on-line, changes can be made compared to what is stated in the syllabus to make the course and exams accessible also in these ways
