Abstract
A qualitative and comparative study was carried out on some locally sourced oils melon oil Africa elemi oil and Africa locust bean oil to evaluate suitability as substitute quenching media to mineral-based oil. The cooling ability of the oils was investigated using AISI 1034 medium carbon steel. The effect of heat transfer coefficient on quench severity mechanical properties of the quenched specimens were investigated in the course of the study. Results showed that the peak rate of heat extraction of melon oil Africa locust bean and Africa elemi oil were higher than that of mineral oil. Higher heat transfer coefficient of 1463 1023 Wm2k were obtained for melon oil and Africa locust bean Africa elemi and SAE 40 oil have heat transfer coefficient of 982 and 469 Wm2k respectively. The selected oils can be used as quenchants for medium carbon steel since the oils exhibits better cooling properties and mechanical properties than mineral-based oil.
