Influence of Different Quenching Media on the Mechanical Properties of Mild Steel – A Case Study of Coconut Oil, Mineral Oil, Jatropha Oil, and Water

By E. O. Ajoge and Musa James

Abstract: This study elucidates how local cooling agents, such as coconut oil and jatropha oil, influence the mechanical characteristics of heat-treated mild steel. Tensile testing, Brinell hardness testing, and microstructural analysis were conducted on both heat-treated and untreated samples. The results show observable differences in the heat-treated materials’ mechanical characteristics. Specifically, the yield strength increased across…
