“…The mechanical properties are having positive results with the water quench media compare with the other quenching Medias. Adeyinka Adebayo et al [4] has investigated on the quenching media which effects on the mechanical properties of the heat treated mild steel specimens. Mechanical tests like Tensile test, hardness test and micro structural analysis were carried out and results are recorded.…”

In the advanced planning world, expansive research has incited the improvement of some phenomenal dimensions of steel, every now and again fitting for overhauled limits. Medium carbon steel AISI 1026 is one such assessment, having huge applications in power plants, vehicle and diverse current applications. Diverse warmth treatment forms are utilized to accomplish high hardness and durability, however machinability consequently diminishes. Existing writing isn't adequate to accomplish a harmony among hardness and machinability. The point of this exploratory work is to decide the hardness esteems and durability changes in AISI 1026 steel, when it is exposed to Annealing saw that high toughness value (impact energy) and moderate hardness. Annealed samples oppressed Intercriticle annealing process that implies heated upto upper critical temperature and water quenched. It is seen that the Intercriticle Annealing (ICA) of the specimens after annealing process achieved better results as compared to as received material AISI 1026steel.

This paper described some mechanical properties of aluminum alloy using agro-waste materials such as sawdust, groundnut shell, and eggshell. The sand-casting method was adopted to produce the alloy with 5, 15, 25, and 35% wt. additives. The microstructure of the various samples produced after quenched in water, palm oil, and engine oil was examined while hardness properties were determined. The result obtained shows that hardness values increased with an increase in the addition of sand mold Agro-waste ashes. Samples cast with eggshell ash additive and quenched in water coolant had the highest hardness value of 82.4 at 25% wt. additive when compared with sawdust ash and groundnut shell ash additives. sand-casting enhances the hardness of the specimens and thus, can be used in many engineering applications such as engine blocks and wheels in automotive parts and aerospace components.

“…If outrageous hardness is not needed, mineral oil, whale oil, or cottonseed oil might be utilized in the quenching system all things being equal. The hot metal is being moved to the medium, steam ascends from the metal in incredible volume [4]- [6]. Motagi [7] performed some studies showing that low carbon steel such as mild steel can be fortified through heat treatment while extinguishing after heat treatment works on the mechanical properties of the steel.…”

Quenching is a swift way of returning metal back to ambient temperature in order to acquire a certain property. Although it is often used to enhance the hardness of metals and their micro-structure, it equally causes a serious variation in the mechanical and physical properties of the metals. This research focuses on quenching media's effect on the microstructure and mechanical properties of a 150mm x 80mm x 8mm welded mild steel plate through microscopic examination, metallography mounting, surface grinding, and surface polishing. Microstructural analysis with hardness and impact test was carried out on the steel plate using water, air, and oil as the quenching media. The results of the test show the Vickers Pyramid Number (HV) for water, oil, and air to be 284.2, 270.9, and 262.2 HV for the base metal, heat affected zone (HAZ), and weld metal (WM), respectively. The amount of energy absorbed by the three specimens during fracture is 23.12, 25.27, and 26.83 J, respectively. The test further indicates that the water-quenched media exhibited mostly martensitic structures and held back austenite with many structures of cementite while the oil and air media exhibited martensite phase and refined grains structures individually. It is therefore concluded that air is more suitable to cool the weld metal for damping applications in engineering.
