The molten alloys were cast in the space between concentric cylinders composed of a graphite mold and cylindrical alumina stirrer. Conventional single casting without agitation produced coarse primary silicon crystals, and the primary silicon size decreased monotonously as the rotation speed of the stirrer increased. On the other hand, agitation by the stirrer inhibited the proper refinement mechanism of Duplex Casting.日本鋳造工学会2005-08-25jpnjournal articleVoRhttp://hdl.handle.net/2115/74712https://doi.org/10.11279/jfes.77.5421342-04292185-5374AN10514770鋳造工学Journal of Japan Foundry Engineering Society778542546https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/74712/1/Chuzo.77.542.pdfapplication/pdf991.82 KB2005-08-25
