... of cottonseed, sunflower, corn, canola, and soybean oils. To assess the relative quenching performance of these different vegetable oils, cooling curve analyses was conducted according to ASTM D6200 at series of quenchant bath temperatures: 40, 60, 80, 100, and 120°C. For comparison, cooling curve analysis...

When examining actual quenching practice, it is important to correlate cooling performance of the quenchant and the cooling and transformational behavior of steel, especially if there is a variation of cooling rate during the quenching process. This behavior is very...
