摘要

摘要: 研究了鋼中不同夾雜物對Sb的析出和高溫氧化過程中富集行為的影響.Fe-1.5%Sb合金1100℃水冷試樣中Sb在鋼中主要析出位置是晶界.與單一的氧化物夾雜相比,硫化錳是更為有效的Sb異質形核核心,且Sb析出相成分組成接近于FeSb相.實驗結果與二維錯配度理論計算結果相一致.通過降低氧含量,鋼中加入Ti變質硫化錳夾雜等方式,增加了MnS數量,使得更多的Sb在夾雜物上析出,從而減少鋼中Sb的偏析和固溶量,改變Sb在鋼中的析出位置.

Abstract: The effects of different inclusions on antimony precipitation and enrichment in steel during high-temperature oxidation were investigated. It is found that in the Fe-1.5%Sb alloy specimen, antimony-enriched phases precipitate at grain boundaries after water-quenching at 1100℃. Manganese sulfide is more favorable for antimony precipitation than oxide inclusions. The chemical composition of antimony-enriched phases is close to that of FeSb, which is consistent with the result calculated by the disregistry of lattice parameters between antimony particles and the inclusions. Reducing the oxygen content or adding Ti in steel can increase the amount of manganese sulfide and promote antimony precipitation, thereby decrease the amount of antimony segregation and solid solution, and change the precipitation location of Sb in steel.
