Figure 10. Stress and temperature profile during Gleeble on-heating ductility test of nickel-based superalloy with insert microstructure observed adjacent to the fractured surface. The arrows on the plot illustrate the correspondence between the temperature where liquation of the precipitates occurs and the abrupt drop in stress level
