摘要：
Different amounts of rare earth yttrium were added to H13 die steel to study the effect of Y on the type，form，size and composition of inclusions in steel. By adding Y to the electroslag and remelting and smelting them，the laboratory obtained H13 electroslag ingots with Y contents of 0.0008%，0.006% and 0.012%. The analysis was carried out by means of OM，SEM，ASPEX and thermodynamics software. The results show that the main inclusions in H13 die steel without any Y are MgO·Al2O3 covered by（Cr，V，Mo）C. The inclusions in H13 die steel with 0.0008% Y are mainly YAlO3 covered by（Cr，V，Mo）C. The inclusions in H13 die steel with 0.006% Y are mainly YAlO3 and YAlO3 covered by（Cr，V，Mo）C. The inclusions in H13 die steel with 0.012% Y are mainly Y2O3，YS-Y2O3 and Y covered by（Cr，V，Mo）C. When 0.012% of Y is added，inclusions smaller than 5 μm account for more than 96% of the total. © 2023 Chinese Society of Rare Earths. All rights reserved.
