This paper investigates the effect of the addition of 0.2 g/L of TiO2 nanoparticles in water on deformation cylinder with the length of 66 mm and a diameter of 12.5 mm made of steel EN 90MnCrV8. Experiments were conducted with vertical cylinder immersion into the water or nanofluid, with and without agitation. Cooling curve of tested quench media are recorded by the ivf SmartQuench system and it is analyzed in the computer program ivf SQintegraver4.0TM in aim to determine cooling parameters and the heat transfer coefficient (HTC). The HTC was used in a finite element (FE) simulation of deformation in quenched cylinders. The diameter of cylinders was measured over cylinder’s height and compared with the results of FE simulations. The measured change in diameter over cylinder’s height showed significant dependence of deformation from cooling conditions and the quenchant used.
