摘要: Several grain sizes were obtained by heat treatment at different temperatures for interstitial-free (IF) and 2.25 Cr-1Mo steels. Samples of the steels with different grain sizes were aged at 600 and 680° C for IF steel and 520 and 560° C for 2.25 Cr-1Mo steel for sufficient time to achieve their equilibrium grain boundary segregation. The grain boundary concentrations of phosphorus were examined using Auger electron spectroscopy. At the same aging temperature, the boundary segregation of phosphorus increased with increasing grain size …
