摘要: 采用金相顯微鏡和掃描電鏡,研究并討論了鈮、鈦單穩定條件下,高純鐵素體不銹鋼的凝固組織及夾雜物的狀態.結果表明:單鈦穩定相對單鈮穩定能顯著提高鐵素體不銹鋼的等軸晶比例,鈮更能起到細化晶粒的作用.鈮、鈦單穩定條件下鐵素體不銹鋼中夾雜物的分布和類型存在較大的差異.

Abstract: The solidification structure and inclusions of high-purity ferritic stainless steel stabilized with Ti or Nb were investigated by the optical microscopy (OM) and scanning electron microscopy (SEM). The results showed that Ti could increase the isometric crystal ratio and Nb could refine crystal size in the high-purity ferritic stainless steel. The composition and status of inclusions were all significantly different in the high-purity ferritic stainless steel stabilized with Ti and Nb,respectively.
