Brenner, S. S.

During the period July 1, 1988 to December 31, 1988 considerable progress has been made in characterizing the distribution of solute atoms in nickel aluminide. Topics covered by this report are: controlled backpolishing of FIM needles; analysis of grain boundaries in B-doped Al-rich Ni/sub 3/Al; clustering of boron in B-doped, Al-rich Ni/sub 3/Al; segregation of carbon to grain boundaries in Ni/sub 3/ Al; site occupation probability of tantalum in Ni/sub 3/Al; and atom probe analysis of Co/sub 3/Ti.
