Simulation of hardening in high purity niobium single crystals during deformation

In the present work, the deformation behaviour of a niobium single crystal has been simulated using crystal plasticity theory. Unlike face-centered-cubic crystal, body·centered-cubic crystal has three families of slip systems (110)[111], (112)[111] and (123)[111] with a total of 48 slip systems. Therefore interdependency off the crystal parameters of each family of slip system plays an important role
