GRAIN BOUNDARY SEGREGATION OF BORON. AN EXPERIMENTAL AND THEORETICAL STUDY

Abstract
Boron grain boundary segregation and its influence on the precipitation behaviour and the distribution of elements in the boundary region have been studied in austenitic stainless steels and nickel using a combination of microanalytical methods (SIMS, TEM, EDS, FIM, AP and IAP) and computer simulations. Experimental and theoretical results on boron segregation are compared and it is shown that the segregation is mainly of the non-equilibrium type. The effects of boron segregation on the precipitation behaviour and the boundary composition are exemplified and discussed.
