Description

Quenching Research Centre (QRC) has been established at the beginning of 2010 by the financial support for excellence of the Ministry of Science Education and Sport, of the Republic of Croatia. The main investigation and research possibilities and potentials of the QRC are: quenching in liquids or in a salt bath and cooling by high pressure gases. As a result of long term research the Temperature Gradient System has been designed, together with a unique cylindrical probe of 50 mm Dia. × 200 mm instrumented with three thermocouples. Another device used at the Centre is IVFSmartQuench system according to ISO 9950 standard, using a quenching device with agitation according to ASTM D 6482 standard. That equipment is used to investigate liquid quenchants and process parameters, including development of new quenchants: water, oil and polymer based nanofluids agitated by ultrasonic vibrations, as a novel technology. QRC is also equipped with a unique high pressure gas quenching facilities providing the hardware for controllable heat extraction. The aim of using that equipment is to develop the method for measuring hardenability of high-alloyed steels when they are gas quenched, where Jominy test is not applicable. QRC is also one of initiators and an active participant in the project Global database on cooling intensities of liquid quenchants which is coordinated and conducted by International Federation for Heat Treatment and Surface Engineering (IFHTSE).
