Course abstract
In the study course, students get acquainted with the structure of materials used in mechanical engineering, physical and mechanical properties, marking, heat treatment methods and application. Learns to determine the mechanical and technological properties of materials develop methodology and perform heat treatment. Gains skills in recognizing materials, choosing, making specific machine parts.
Learning outcomes and their assessment
Knowledges - properties of mechanical engineering materials and their relation to the structure - 1st test; influence of heat treatment on properties - 2nd test;
Skills - to recognize materials according to their chemical composition, to develop heat treatment technology, to find application - laboratory works; Competences - rational choice of materials in specific operating conditions and possibilities of changing material properties using heat treatment – home work.
