Investigation of the Effect of Cow and Fowl Dung as Quench Medium on the Tensile and Hardness Properties of Low Carbon Steel

Abstract

This study investigates the influence of cow dung and fowl dung quenching media on the tensile and hardness properties of low carbon steel. The samples were heated to 850°C, soaked for 30 minutes, and quenched in the respective organic media. Tensile tests were carried out using a Universal Testing Machine, while hardness properties were interpreted based on standard heat treatment behavior. Results revealed that the organic quenchants significantly affected the strength and ductility of the steel. The cow dung quenched sample exhibited a moderate increase in yield and tensile strength compared to the as-received sample, while the fowl dung quenched sample showed the highest ultimate tensile strength and hardness, indicating a more effective quenching medium. The use of organic materials as quenching media demonstrates an environmentally friendly and cost-effective alternative to conventional quenching oils.
