State VL - 21 IS - 2 SE - Scientific articles DO - 10.15330/pcss.21.2.272-278 UR - https://scijournals.pnu.edu.ua/index.php/pcss/article/view/3578 SP - 272-278 AB - <p>Interaction between the components in the Ho-Fe-Sn ternary system was studied using X-ray diffractometry, metallography and electron microprobe analysis. Isothermal section of the phase diagram was constructed at 670 K over the whole concentration range. Component interaction in the Ho-Fe-Sn system at 670 K results in the existence of one ternary compound HoFe<sub>6</sub>Sn<sub>6</sub> which crystallizes in the YCo<sub>6</sub>Ge<sub>6</sub> structure type (space group <em>P</em>6/<em>mmm</em>, <em>a</em>=0.53797(2), &nbsp;&nbsp;<em>c</em>= 0.44446(2) nm). The interstitial-type solid solution HoFe<em><sub>x</sub></em>Sn<sub>2</sub> (up to 8 at.% Fe) based on the HoSn<sub>2</sub> (ZrSi<sub>2</sub>-type structure) binary compound was found. Solubility of Sn in the HoFe<sub>2</sub> binary (MgCu<sub>2</sub> structure type) extends up to 5 at. %.</p> ER -
