Abstract
The intention of postdoc applied research project is to develop and construct the prototype of the measurement system that enables in-situ monitoring of heat treatment of metallic materials. The measurement system will consist of the measurement cell and the mathematical-physical models. The measurement cell will enable performance of the in-situ measurements of electrical resistance of the specimen during heat treatment on the basis of the four probe method. The measured electrical resistance will be then transformed with the previously defined mathematical-physical models into the instantaneous microstructure of the specimen. The conversion of electrical resistance into the time dependent microstructural changes will enable us to trace the kinetic and the mechanisms of the phenomena during heat treatment of metallic materials. To accomplish this, the process of internal oxidation will be divided into the sequence of the key partial reactions that will be presented in the model as the parallel and/or serial connected time variable resistors in the electrical circuit. The measurement system will be developed in cooperation with a company Bosio d.o.o., which is the leading manufacturer of the furnaces for heat treatment in Slovenia. With the measurement system the in-situ monitoring and regulation of different heat treatment procedures (normalization, recrystallization, case-hardening, nitridation, tempering, …) will be enabled in the wide temperature range.
