Abstract

With 0.018% content in the crust, pure nickel N6 has excellent conductivity, hot conductivity, and corrosion resistance. At present, it has been widely used in chemical, nuclear, marine, and aerospace fields. However, there are few studies on deformation behaviors and mechanical properties of pure nickel N6 at room temperature. In this paper, cold deformation behaviors and mechanical properties of N6 were studied by tensile, compressive, and impact load experiment at room temperature. With the increase of strain rate, it was found that the work hardening index increases gradually and the strength coefficient showed an upward trend, which basically followed the law of parabolic hardening, and its constitutive equation was obtained after the modification of strain rate. Observation of fracture by scanning electron microscope (SEM), it was found that the tensile fracture way of N6 changed from brittle fracture to ductile fracture and the impact fracture mechanism was both ductile fracture and brittle fracture. This study may lay a foundation for the cold working process of pure nickel N6.
