Grain boundary diffusion of "%n in Ni was measured between T = 673 and 1182 K using microtome sectioning and a well type Ge-detector of large efficiency and high energy resolution. In this large temperature range s6D,, varies over six orders of magnitude. The Arrhenius plot of s6D,, shows a remarkab
This paper reports a study of grain boundary segregation of antimony and nickel in iron. These results show that nickel additions to the matrix increase antimony segregation. This observation is in agreement with previously reported work. Antimony additions to the matrix or segregation to the grain
