J. Cermak et al., INFLUENCE OF BORON ON NICKEL GRAIN-BOUNDARY SELF-DIFFUSION IN NI3AL INTERMETALLIC, Physica status solidi. a, Applied research, 158(1), 1996, pp. 35-38
Grain boundary diffusion of Ni-63 in pure and boron-doped Ni3Al interm
etallic was studied at temperatures 833 and 893 K using the residual a
ctivity method. The decrease of the triple product P with increasing b
oron concentration was observed.
