Sažetak
The Ni-base superalloys Nimonic 80A gains its appropriate microstructure and high temperature strength through precipitation hardening. In this paper, the results of mechanical testings are presented for temperature range from 25 to 850°C for the Nimonic 80A superalloys. The variation of ductility properties in dependence of temperature has been demonstrated by analysis on the stereo, optical and scanning electron microscopy and results of tensile test. It was found that different fracture mechanisms occure in a different temperature ranges. Brittle fracture was dominant at high temperatures and a significant proportion of ductile fracture at room temperature was observed.
