. that no diffusion from the grain interior appears and that the intercrystalline 
sulphide sulphide is not caused by a sulphur diffusion from inside to the solidified grain 
boundaries. 
oundaries 
250°C for It seems that the sulphur originates from the segregation at solidification, but 
ied steel the results of the investigations have not been sufficient yet to draw a final 
conclusion where intercrystalline sulphide really originates from during the 
cooling process after solidification.
