Content of the short-term learning experience
Lectures:
Steels are the most important metallic material. Many steels get their final properties from heat treatment. Therefore, knowledge of heat treatment and mastery of the basic skills that enable heat treatment to be designed and carried out is essential in many branches of the metalworking industry.
The lectures will briefly cover the basics of diffusive and non-diffusive phase transformations in solids, metal hardening mechanisms, heat and material transfer in heat treatments. Heat treatment aggregates, types of atmospheres.
The basic types of steels and the use of phase and transformation diagrams in the design of heat treatments will be presented.
Processes in steel cooling and tempering. Soft annealing. Normalisation. Quenching. Step hardening. Surface hardening. Polishing.
Thermochemical treatment (nitriding, cementing, boriding, etc.). Heat treatment failures, their causes and their correction.
Exploring Temperature Measurement Methods for Monitoring Heat Treatment Processes. The lectures will cover the following topics: (i) the physical effects underlying temperature measurement, (ii) contact and non-contact measurement methods, and (iii) various types of measuring probes or sensors.
Exercises:
Practical heat treatment of selected steels. The emphasis is on the participants to determine the basic parameters of the treatments on the basis of knowledge of the relevant phase and transformation diagrams and literature data (e.g. handbooks), to carry out the treatments and mechanical tests on the samples, and to carry out metallographic analysis.
During the practical training sessions, participants will gain hands-on experience with thermocouples, exploring their operation based on the Seebeck effect. They will utilize thermocouples to measure the temperature profile of the furnace and to monitor the heat treatment of the workpiece using both direct and indirect temperature measurement methods.
