	1	INFLUENCE OF TIN ON THE HOT DUCTILITY OF A LOW-CARBON STEEL显示文摘The influence of tin on the hot ductility of a 0. 15wt%C steel is investigated using a continuous-casting thermal simulator with three cooling rates. Tin can apparently deteriorate the hot ductility of the steel. Non-equilibrium grain boundary segregation of tin occurs during cooling and plays an important role in reducing the hot ductility of the steel. There is a critical cooling rate for the Sn segregation being between 5 and 20K/s.	Z.X.Yuan J.Jia A.M.Guo D.D.Shen S.H.Song J.Liu	2003	Acta Metallurgica Sinica(English Letters)2003，16，6：	2
	2	ANTIMONY GRAIN BOUNDARY SEGREGATION AND ITS SUPPRESSION BY CERIUM IN Fe-2%Mn-Sb STRUCTURAL STEELS显示文摘Antimony grain boundary segregation in Fe-2%Mn-Sb structure steels has been studied through measurements of the ductile-brittle transition temperature in conjunction with scanning electron microscopy, Auger electron spectroscopy and secondary ion mass spectroscopy. The research result reveals that during tempering or ageing after quenching at 980C, Sb segregates to grain boundaries with both equilibrium and nonequilibrium natures and brings about temper embrittlement in the steels. Cerium can relieve temper embrittlement of the steels and its segregation to grain boundaries -05 play an important role in reducing this embrittlement.

	3	PHOSPHORUS GRAIN BOUNDARY SEGREGATION IN A P-DOPED 2.25Cr1Mo STEEL显示文摘Grain boundary segregation of phosphorus during tempering at 540℃ after quenching from 980℃ is examined for a P-doped 2.25Cr1Mo steel by means of Auger electron spectroscopy. The solute-boundary binding energy and the diffusion coefficient for phosphorus are determined by virtue of the measured segregation kinetics along with the equilibrium segregation theory. The obtained values of the above parameters are discussed with comparison to those found in the literature for low-alloy steels.
