Learning outcomes of the course unit

The subject brings to the students a basic knowledge of heat and chemical-heat treatment of the ferous and non ferous alloys and a basic overwiew of the used plants and media.

Prerequisites

The material science and physical metalurgy in the extent lectured duering the passed study, with rlationship to physics, hydromechanics and mathematics

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

To acquire a credit, a student should to take part at all of the seminars and laboratory works, his active approach to the study and all of the written protocols refering, especialy with respect to the knowledge of their meaning. Eventualy absence should be compensated with the aditional work on base of the teachers compliance. The examination is take placed in written and verb noun form. A student should show a good overwiew and some detail knowledge of the topics examined.

Aims

The aim of the subject is to acquaint the students with the basic forms of technigues, media, equipment and other means used in current plants of heat treatment. The task of the subject is to reach of fully understanding of heat treatment importance for machinery production, and acquisition of basic production procedures.

Specification of controlled education, way of implementation and compensation for absences

The seminars and laboratory works are obligatory. In case of the absence, it is necessary to compensate the theme after the teacher compliance. In case of the absence which is planed (some serious family merits f.eg.), it is necessary to agree the matter with the teacher beforehand
