N2 - This paper provides a comprehensive review of current efforts on design of ductile polycrystalline Ni//3Al alloys. Microalloying has proven to be very effective in alleviating the grain-boundary embrittlement problem. The ductility and fabricability of Ni//3Al (24 at. % Al) are dramatically improved by adding a few hundred parts per million of boron. The beneficial effect of boron is related to its unusual segregation behavior as predicted from the theory of grain-boundary cohesion developed by Rice, based on thermodynamic analyses. Alloy stoichiometry strongly influences grain-boundary chemistry, which, in turn, affects the boundary cohesion and overall ductility of Ni//3Al.
