High-Temperature Corrosion Fatigue of a Ferritic Ductile Cast Iron in Inert and Corrosive Environments at 700ºC

Mostrar todas las versiones(2)

In the present work, low-cycle fatigue testing of a ferritic ductile cast iron named SiMo51 has been carried out in three atmospheres: argon, air and a synthetic diesel exhaust-gas at 700C. The fatigue life was reduced up to 80% in the worst case. Two crack growth mechanisms were observed and direc...
