“…Nanofluid application is primarily applied in heat transfer fluid due to the superior thermal conductivity. A specific application of the heat transfer fluid is in the quenching medium during the heat treatment of steel (Agboola et al, 2020;Kresnodrianto et al, 2018;Ikubanni et al, 2017). Improving steel properties, particularly hardness, can be achieved by quenching it from the austenitizing temperature, transforming the microstructure from Austenite to the Martensite phase.…”

In the steel heat treatment industry, quenching is a critical stage for enhancing the characteristics of steel. However, the lack of adherence to appropriate procedures, especially in quenchant selection, can lead to cracks or distortion. Quenchant selection is based on the required cooling rate for the specific steel being quenched. Cooling rate of the quenchant is primarily determined by the thermal conductivity of the fluid. This conductivity can be modified by dispersing stabilized solid particles, typically in the nano-scale range, thus forming a nanofluid. It is important to note that a higher conductivity will increase the heat transfer characteristic and vice versa, hence, cooling rate can be controlled by adjusting the amount of the dispersed particle. In this study, the dispersed particle and surfactant used was multi-walled carbon nanotube (MWCNT) and polyethylene glycol (PEG), respectively. The concentrations of the dispersed particle were 0.1, 0.3, and 0.5 weight%. Furthermore, the surfactant was added at 3 -30% on each particle variation. The results showed that the highest thermal conductivity of 0.68 W/mK was achieved at 0.5% MWCNT and 5% PEG. This translated into better steel properties, as it led to a hardness of 48 in Hardness Rockwell C-scale (HRC) compared with the water-quenching technique. A higher percentage of PEG surfactant decreases the thermal conductivity of the quenching medium and steel hardness. This decrease was attributed to the high viscosity of the medium. In conclusion, adjusting the particle and surfactant concentration allows for the optimal quenching medium, offering enhanced steel properties.

“…In order to have those mechanical properties, heat treatment can be used to design the materials with the desired properties. Heat treatment can be defined as a combination of two procedures, heating and cooling metal or alloy in solid state which arranged in time intervals in order to alter their physical and mechanical properties to meet desired engineering applications [4]. The process is started by annealing at higher critical temperature, hold for a certain time, followed by a rapid cooling process or known as quenching.…”

Selection of quench media is important as it depends on the hardenability of the metal alloys, component’s thickness and geometry. Recently, oil and water are frequently used as a quench media in heat treatment industries. Improper quench media will cause the material to become brittle, suffers from geometric distortion, or having a high undesirable residual stress in the components. Oil was used as the fluid base in this research as the main observation focus. To obtain nanofluids and explore thermal conductivity and stability of nanofluids, the two-step method was introduced to prepare the nanofluids with 4 types of different cooking and waste cooking oil as a base fluid (Palm oil, sunflower oil, canola oil and corn oil). TiO2 powder will be mixed with oil fluid by using magnetic stirrer for 1 hour and ultrasonic bathing. Observation method used in 30 days with thermal conductivity and zeta potential to evaluate stability of each nanofluid specimens. Heat treatment onto carbon steel applied and the sample were heated at 950°C for 90 minutes and then quenched in difference oils. Microstructure and hardness analysis applied to get the result. It can conclude, adding nanoparticles in oil base fluid will enhance thermal conductivity and improve thermal performance of heat transfer of the base fluid. Quenching process with oil-based nanofluid will produce martensite structure and waste sunflower and corn oil with TiO2 it's not stable after 30 days observation but the palm and canola oil with TiO2 can achieve the highest hardness test and thermal conductivity.
