Course detail

Heat Treatment of Metalic Materials

FSI-WST Acad. year: 2021/2022 Winter semester

The subject "Special technigues of materials treating" brings knowledge of progresive methods of bulk and surface heat and chemical heat treatment of metals. It deals with aplications of non coventional means of heating, heat-difusional processes like sintering and hightemperature isostatic pressing and others. The modern driving systems of technology plants, essentials of the quality controll in the heat and chemical heat facilities and the ekological aspects of the used technologies are described. The subject amplifies the "Technology and technigues of heat treatment of metals" (DTZ) and materials aimed subject in the earlier years of study.

Learning outcomes of the course unit

The passing through a subject WST study, brings to the students the wiew over the modern technigues and technologies used for the metalic materials treating from of the point of wiew of their principles, use, the properties achieved, industrial conditions of production, economy aspects, quality controll systems basics and some environmental questions. The subject graduates should be able to assort the proper combination of material and suitable treating, with respect to function of the machine part or tool, including the economy and environmental aspects of the production.

Prerequisites

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

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 improve the student´s knowledge in the field of the advanced technologies used for achieving of the needed materials properties, namely in the high performance aplications, an to show to the students the industrial point of wiew of the aplication of physical and teoretical principles formerly presented duering their study. The other task of the subject is to acquaint the students with the Quality systems controll basics and the ekological questions bound to the technigues described.

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.
