3.3. HRC hardness as a function of the austenitizing temperature
Table 3 shows the measured values of Rockwell profile for the
for the three austenitizing temperatures (average of four hardness
measures) which is shown in Fig. 8 and the correlation with the
Vickers hardness (HV). It is observed that there was an increase
in the hardenability with higher austenitizing temperature,
according to Fernandino et al. [16] (in a nodular cast iron at different austenitization temperatures) and Llewellyn and Hudd
[17] (at the Jominy test applied in a steel alloy).
Hardness in scale HRC is placed and the values in parentheses
are outside the recommended range and are given only for comparison
purposes.
