It is demonstrated that the dominative process controlling the motion of the reaction front gradually changes from the solid–solid transformation to the secondary solid solidification as the moving velocity of solid–solid interface decreases. On the other hand, the local shape of the triple junction is mainly determined by the balance between the interfacial energies regardless of the difference in the moving velocity of solid–solid interface.Iron and Steel Institute of JapanJournal Articleapplication/pdfhttp://hdl.handle.net/2115/75419https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/75419/1/ISIJ%20Int.%2050%2812%29_%201879-1885%20%282010%29.pdf0915-15591347-5460AA10680712ISIJ International5012187918852010-12-15enginfo:doi/10.2355/isijinternational.50.1879著作権は日本鉄鋼協会にあるpublisher
