() is the transition temperature in () between the film-boiling (vapor-cooling) stage and the nucleate boiling stage of the cooling process. () is the transition temperature () between the nucleate boiling stage and the convective cooling stage of the cooling process. (3) Hardening power (HP) was calculated using the Bodin-Segerberg equation for unagitated oils: HP 91.5 1.34 10.88500 3.85 . (4) Hardening Power (HP) was calculated (2) developed for agitated polymerquenchants; HP 3,54 550 12.30 330 168. (5) The core hardness values were determined on the 1045 steel test specimens quenched as shown in the table. These hardnesses were determined after quenching. |
