Rules for evaluation and completion of the course
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
Aims
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.
