Abstract
The deformation of body-centered cubic (b.c.c.) metals such as W, Ta, and Mo is complicated both by complex deformation mechanisms at the atomic scale and by microstructural variations at the microscale. In this paper, we develop a multiscale model for low-temperature deformation in b.c.c. metals. This model integrates atomic-scale observations into a single crystal constitutive relationship that is implemented in a polycrystal plasticity grain-scale simulation. We determine that the details of deformation at the microscale differ substantially between b.c.c. and f.c.c. metals.
