Interfaces and Planar Defects

A careful, quantitative study on grain boundary segregation, boron segregation in austenitic stainless steels of types 316L (with 206 at. p.p.m. of boron, and with 5 at. p.p.m. of boron) and Mo-free 316L (75 at. p.p.m. boron), has been reported by Karlsson, Norden, and Andren36 using a combination of TEM, FIM, AP and IAP techniques. Concen- 

Interface segregations in other materials have also been investigated. Horton Miller41 studied segregation of boron to the grain boundary and antiphase boundary in rapidly solidified ordered Ni3Al alloy doped
