摘要：
A combination of transmission electron microscopy, field-ion microscopy, and atom-probe microanalysis was used to study grain boundary segregation of boron and its influence on the elemental distribution in the boundary region in AISI type 304 (UNS S30400) austenitic stainless steel. Non-equilibrium segregation of boron is shown to prevail with a maximum concentration at the grain boundary and a tail of decreasing concentration away from the boundary. The effects of boron segregation on the elemental distribution of carbon, phosphorus, and chromium are also discussed.
