dc.description.abstractThis study was on the development and performance evaluation of a Jominy end-quench apparatus used for the determination of the hardenability of metals. The fabrication of the apparatus was undertaken bearing in mind the availability of the materials and cost implications of the apparatus. Stainless steel was used for the water prone areas to avoid corrosion while mild steel was used for other areas that are not exposed to water or other quenching fluids during operation. Fifty-four samples were prepared for the performance evaluation on the developed Jominy apparatus and were heated to temperatures of 850 0C, 900 0C, and 950 0C before quenching in the apparatus. Water and brine (pH values 6.5 and 5.6, respectively) were used as quenchants in the determination of hardenability of the specimens. The results obtained from the tests showed that Brinell hardness values reduced as distance from the quenched surface increases. Water quenched samples produced higher hardness value at lower quenching temperature while brine quenched specimens had higher Brinell hardness value at higher heating temperatures. When compared with the standard, the results obtained were very close which make the developed apparatus suitable for hardenability test of metals.en_US
