Rules for evaluation and completion of the course
Requirements to acquire a credit:
-Active participation in seminars, requiring theoretical preparation.
-Submission of lab reports with an emphasis on understanding their content. The reports are partially completed during the seminars.
-Participation in a excursion and, if applicable, fulfillment of alternative requirements.
Exam: Written and oral, during which the student demonstrates both a comprehensive overview and detailed knowledge of the covered topics. The final grade is determined according to the ECTS scale.
Seminars are mandatory; absences are handled individually.
Aims
The aim of the course is to familiarize students with the basic types of technologies, environments, equipment, and other means used in heat treatment facilities. Students should understand the importance of heat treatment for mechanical engineering production and master the basic technological procedures.
The course Technique and Technology of Heat Treatment enables students to acquire knowledge of basic heat treatment and checial-heat treatment procedures for ferrous and non-ferrous metals, as well as the equipment and environments used to carry them out.
Study aids
Study materials are provided to students during the semester via e-learning.
