%X The embedded atom type potentials and static relaxation method combined with a steepest decent computational technique have been used to simulate the interaction be- tween the grain boundary and dislocations in Ni_3Al. The focus has been placed on the ener- getic features of the interaction, the distortion of grain boundary structural units and the dis- location core structures near the grain boundary. Implication has also been made on the re- sults for understanding of the mechanism responsible for boron-enhanced ductility.
