A numerical study for the estimation of a convection heat transfer coefficient during a metallurgical “Jominy end-quench” test

Influence of the cooling rate on the texture and the microstructure of Zircaloy-4 studied by means of a Jominy end-quench test

“…The best match is obtained for h¼11,000 W/(m 2 K). This value is close to the value used for steel above 600 1C in a related study [24]. -values of _ T are calculated on the whole length of the testpiece.…”

Numerical – Experimental correlation of microstructures, cooling rates and mechanical properties of AISI 1045 steel during the Jominy end-quench test

“…The underlying mathematical model for the austenite-pearlite phase transition is based on Scheil's Additivity Rule and the Johnson-Mehl equation. Le Masson et al [2] have developed a numerical method for the two-dimensional estimation of the convection heat transfer coefficient for a rapid metallurgical heat treatment. Mathematical modeling of austenite decomposition has also been investigated by Smoljan [3].…”

Prediction of hardness at different points of Jominy specimen using quench factor analysis method

“…Austenitizing temperature of 870 • C was used and then the model was cooled for a period of 600 s (ASTM, A255). Also, the following film coefficient change (h) of water was used to consider heat exchange between water and the specimen surface (Masson et al, 2002):…”
