The goal of the course is to gain knowledge of the basic principles that determine physical, metallurgical and chemical phenomena involved in the design of metallic materials.
The course aims to deepen students' knowledge of the fundamental characteristics of metallic materials and the chemical-physical and metallurgical phenomena involved in their design, also through practical examples.
The course includes theoretical lessons, for a total of 4 credits.
Metals and alloys. Notes on the metallic bond. Solid solutions, interstitial and substitutional, ordered and disordered. Intermetallic compounds: structure and properties. Structure-sensitive and structure-insensitive properties. The ideal and the real crystal. Crystal defects and their classification. Point defects: vacancies, interstitials, impurities. Defect concentration at the equilibrium state. Experimental study of point defects at thermal equilibrium and out of equilibrium state. Notes on linear defects: dislocations. Other types of 2D and 3D defects: surfaces, grain borders, precipitates, vacancy precipitation. Influence of defects on the properties of metallic materials. Diffusion in metals: macroscopic and microscopic aspects. Volume diffusion. Diffusion in homogeneous and eterogeneous systems. Diffusion coefficient and its experimental dependence from temperature. Atomic mechanisms of diffusion. Diffusion in alloys. Short circuits of diffusion. Effects and applications of diffusion phenomena: powder metallurgy. Homogeneous and eterogeneous solid state phase transitions. Phase transitions without diffusion.

Starting from March, 1st, 2021, according to the timetable shown at http://www.chimica.unige.it/didattica/Home_SC or https://corsi.unige.it/9018 )
The exam is oral,it is always conducted by two teachers and lasts approximately 45 minutes
With the exam description mentioned above the Commission can verify with high accuracy the achievement of learning outcomes of teaching. When goals are not achieved, the student is asked to deepen the study and to ask further explanations to teachers.
