Diagram Description: Duree de chauff. - Time to temperature, Duree d'austenit. - Time while austenite, Temperature d'austenit. - Austenitizing temperature, Grain austenit. - Austenite grain size, Duree du refroidissement entre 800 et 500oC - min - Cooling time between 800 and 500oC minutes , Durete Vickers (30 kg) - Vickers hardness (30 kg load), kg/mm2 - Units for HV test.
The x-axis is not a simple plot of time and, therefore, cooling curves are not superimposed over diagrams. Instead, the x-axis plots the time required to cool from 800 to 500oC, which is related to the cooling rate. Because of this manner of graphical presentation, the transformation is given along vertical lines, rather the usual superimposed cooling curves. Also because of this construction, it is possible to plot room tmeperature hardness as a function of the 'half-cooling' time with a single curve.
