Abstract

This work is a contribution to understand the hot ductility drop mechanism of the Fe36Ni alloys (Invar). In contrast to the literature data, the present results show that sulfur alone causes a hot ductility loss. The precipitates, especially BN, only increase the damage of the material by multiplying the cavity nucleation sites. The nucleation of intergranular microcracks results from the decrease of the grain boundary cohesion associated with both the interfacial sulfur segregation and the contribution of grain boundary sliding to plastic deformation. Sulfur strongly segregates on the tip sof these internal cracks and decreases the propagation energy of cracks, thus leading to the material damage. The ductility recovery at high temperatures results from grain boundary migration and only dynamic recrystallization permits such a motion.
