A Comprehensive Study of the Relationships between Hardenability and Heat Transfer in a Jominy Test Sample

Öz

Quenching is that the steel is quickly cooled in a quenching medium from the austenetising temperature, typically in between 845 and 870 °C. Jominy end quench test is a standard test used to characterize hardenability of steels. In this study, 1050 steel is quenched with Jominy end quenched test. Thermocouples were placed on the sample to determine the cooling rate in Jominy sample quenched end, and is investigated the relationship between heat transfer and hardenability. The relations among critical cooling rate, heat transfer and hardness is determinated in Jominy sample for 1050 steel. At the point where the maximum hardness was observed that the maximum cooling rate. Heat transfer quantitative is fastest in 790 °C. This point of temperature is determinated that critical a value for hardenability of 1050 steel.
