Abstract

Microhardness measurements and Auger electron spectroscopy (AES) have been made to study the relation between grain boundary hardening and segregation in alpha iron-tin alloy. It has been found that the grain boundary hardening depends on the grain boundary misorientation and the amount of tin segregation to grain boundaries also strongly depends on the misorientation, increasing with the tilt angle. The excess grain boundary hardening by addition of tin to alpha iron is concluded to be caused by the grain boundary segregation of tin. Grain boundary segregation diagram has been proposed to quantitatively predict the structure-dependent intergranular segregation.
