The objective of the course is to make students familiar with problems of the degradation of materials and with methods for assessing the causes of machine part failures on such a level that they are able to solve the respective problem individually or in cooperation with specialized workplaces.
Students learn to regard materials as chemically and structurally heterogeneous systems, whose behaviour in real operation conditions is influenced exactly by these heterogeneities. The methodology used in seeking the causes of machine part failures will enable students to solve these problems in connection with the interplay of heterogeneous material, type of loading, and action of ambient environment.

Programme N-KSB-P: Quality, Reliability and Safety, Master's
branch ---: no specialisation, 3 credits, compulsory

26 hours, optionally

1. Experimental methods most frequently used in analyses of the causes of failures (metallography – light and TEM microscopy, fractography – macro and micro, inclusive of REM, local microanalysis – EDS, WDS, AES).
2. Degradation of metallic materials in the course of production (metallurgy, welding, metal-forming, machining).
3.Chemical and related structural heterogeneity of metallic materials.
4. Examples of degradation processes in the course of operation (local types of corrosion, corrosion cracking, hydrogen embrittlement, radiation embrittlement, wear).
5. Methodology for assessing the causes of machine part failures, practical demonstrations.
6. Student presentations (see "Exam Form..."), practical demonstrations.
