3.1 Physical characteristics of unalloyed nickel

In the recrystallized state, the physical characteristics of low-C unalloyed nickel such as $\text{Ni}\ge 99\%$ are close to those of Fe :

• Modest tensile behaviour: R _p0.2 = 100 MPa; R _m = 360 MPa ;

• crystallization in the CFC mesh since solidification (T _f = 1,453 °C), giving rise to excellent ductility (A = 40%) at all temperatures and a wide range of work-hardening consolidation;...
