Current investigations at Quenching Research Centre (QRC)
Quenching Research Centre 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: cooling in liquids, salt bath and high pressure gases. As a result of long-term research a new Temperature Gradient System has been designed together with a unique cylindrical probe of 50 mm Dia. × 200 mm assembled with three thermocouples. Equipment used at the Centre is IVF SmartQuench system according to ISO 9950 standard, and a quenching device with agitation according to ASTM D 6482 standard. The equipment is used to investigate new liquid quenchants and process parameters. This includes the development of new quenchants: water, oil and polymer based nanofluids and ultrasonic agitation as a novel technology. QRC is equipped with a unique high pressure gas quenching assembly providing the hardware for a controllable heat extraction. The research in this area aims at developing a method for hardenability measurements of gas quenched steels. Part of the research at QRC is modeling of relative changes of the component dimensions that are analyzed in dependence of five autonomous dimensionless numbers with theirs interactions in aim to find the proper equations for prediction of unavoidable distortions in a transformation free cooling. QRC is also one of initiators and an active participant in the project Global database on cooling intensities of liquid quenchants that is coordinated and conducted by IFTHSE.
