An experimental study of the Fe-Sn-Zr ternary system at 900 °C

The partial isothermal section of the Fe-Sn-Zr system at 900 °C reported in Ref. [7] was completed. As compared with this section, three new ternary compounds were evidenced (Y, C36 and Fe6Sn6Zr), one compound previously reported with a homogeneity domain (X) was shown to consist in fact of two separate compounds with close compositions (X′ and X″). The crystal structure of the previously reported N phase was determined ab initio from powder diffraction data.
