Abstract
Abstract
The shape and geometry of a part influence the cooling behavior during a martensitic transformation; an experimental study carried out on a control Jominy bar was compared with other bars fitted with one, two, and three slots; the results show differences in hardness along the specimen, the hardness with a slit and more is greater than the hardness on a sample without a slit, this is valid on the cooled side of the specimen, the further away from the side cooled plus the difference is minimal; the study was completed with a simulation on bars with and without slits, the results of the temperature contours show an acceleration of the cooling on the cooled side of the bars provided with slits; far from the cooled face the influence of the slits is weak.
