Abstract
The behaviour of boron segregation to grain boundaries in Fe-3%Si has been studied by means of particle tracking autoradiography. The result s indicate that (i) the binding energy between boron atoms and grain b oundaries is 55.7+/-1.7 kJ mol-1; (ii) in contrast to the nature of bo ron segregation in gamma-Fe, no observable non-equilibrium segregation of boron to grain boundaries exists in Fe-3%Si alloy during cooling a nd isothermal holding.
