Abstract The elastic field of a dislocation piercing the interface of an anisotropic bicrystal is obtained for the general case of a dislocation line refracted at the interface. The theory is based on the method of dislocation‐line force fans which reduce the three‐dimensional elastic field of the dislocation in the bicrystal to the superposition of two‐dimensional fields of straight dislocations and line forces in an infinite homogeneous medium. The suggested method should be suitable for numerical calculations of the elastic fields of dislocations in arbitrary bicrystals.
