Effect of 0. 10Cu-0.07As-0.05Sn on segregation in solidification
grain boundary segregation in heat treatment and ductility of low alloying steel (%:0. 15C

0.019P) at elevated temperature have been studied by Gleeble- 1500 hot simulator
scanning electron microscope and Auger electron spectroscopy. Results showed that the segregation of Cu-As-Sn at grain boundary obviously increased the width and depth of depression of Ⅲ brittleness zone and raised upper limit of critical temperature of this zone; there was no-obviously Cu-As-Sn grain boundary segregation in cost billet and there was obviously grain boundary segregation in sample tensile-strained to yield at 850 ℃; and in sample of hot-rolled plate
it indicated the hot deformation promoted grain boundary segregation of residual elements.
