LEARNING OUTCOMES

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.

Teaching methods

The course includes theoretical lessons, for a total of 4 credits.

SYLLABUS/CONTENT

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 2D 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.

Exam description

The exam is oral,it  is always conducted by two teachers and lasts approximately 45 minutes

Assessment methods

With the exam description mentioned above the Commission can verify with high accuracy the achievement of learning outcomes of teaching. The laboratory activities, on which students must submit a written report, are also taken into account. When goals are not achieved, the student is asked to deepen the study and to ask further explanations to teachers.
The CCS ensures the correspondence between the exam topics and those actually covered during the course. To this aim, at the end of the course, the book of the lessons is published in a web site reserved for members of the CCS and student representatives. In this way, students themselves can ensure the adherence to this rule.
