475 °C Embrittlement in a duplex stainless steel UNS S31803
Tavares,S.S.M.; Noronha,R.F. de; Silva,M.R. da; Neto,J.M.; Pairis,S.The susceptibility of a duplex stainless steel UNS S31803 to thermal embrittlement at 475 °C was evaluated by means of mechanical tests (impact energy and hardness), magnetic measurements (hysteresis and thermomagnetic analysis) and scanning electron microscopy. The results show that the material undergoes severe embrittlement and hardening in the first 100 h. The corrosion resistance of the ferrite phase in a ...
