Figure 9: Fractured specimen at a temperature of 25 °C. Surface defects are visible on the specimen. The fracture surface corresponds to ductile rupture. Slip lines intersect in the neck region of the specimen. A small decrease in plasticity was observed at a temperature of 400 °C (Tab. 2 and Fig. 10). The presence of surface defects became more consistent. However, the fracture mechanism remained ductile. Deformations in the neck occurred in different slip planes at an angle of 43°21' (see Fig. 10, Tab. 3), in the plane of maximum tangential stresses.

Figure 10: Fractured specimen at a temperature of 400 °C. Surface defects are more significant. The fracture surface corresponds to ductile rupture. Slip lines intersect in the neck region of the specimen.
