might precipitate in molten steel and solid state, but the precipitation temperature was significantly higher than that of carbides in high-carbon chromium bearing steel. For experimental bearing steels, the volume fraction of inclusions increased steadily with the increase of RE content, but smaller and more dispersed inclusions could be obtained by 0.018% RE content compared with bearing steel......
Alloying Effect of Lanthanum in GCr15 Bearing Steel with Tin and Antimony肖寄光,王福明,李长荣,赵亚斌摘 要:Effect of tin and antimony on hot ductility of GCr15 bearing... that with increasing contents of tin and antimony elements, the hot ductility of GCr15 bearing steel was decreased. Lanthanum can reduce the harmful effect of tramp elements on the hot ductility of GCr15......
