Effect of annealing temperature on phosphorus segregation at grain boundary in a Ti-IF steel

摘要：

　　The concentration of phosphorus at grain boundary of the Ti-IF steel annealed for 180sec at 780℃,810℃ and 840℃ respectively is measured by auger electron spectroscopy(AES).The results show that the segregation concentration of phosphorus at grain boundary decreases with increasing annealing temperature from 780 to 840 ℃.The maximum phosphorus concentration at grain boundary is 13.5at% or so for the specimen annealed for 180sec at 780℃.Most of the grains are intergranular crack and there are a few secondary crack for the samples annealed at 780 ℃ and 810 ℃.The grains grow up and the cleavage planes increase with increasing the annealing temperature from 780 to 840 ℃.
