  Decomposition of FeSn intermetallic induced by mechanical milling

  摘要：

  Under mechanical milling (MM) in a planetary ball mill the FeSn intermetallic decomposes with formation of the Fe5Sn3 and FeSn2 phases, which have the highest density among the phases of the Fe-Sn system. This process was investigated using conventional X-ray diffraction, DSC, magnetization and alternative current susceptibility measurements. If the amount of decomposition of FeSn is relatively small (<60%), the milled powder shows superparamagnetic behavior at room temperature. In this case, magnetization curves can be fitted by superposition of two Langevin functions. The particle sizes for the ferromagnetic Fe5Sn3 phase determined from the fitting parameters are in good agreement with the crystallite sizes determined from XRD data and remain approximately constant during MM. The decomposition of FeSn is attributed to the effects of local temperature and local pressure produced by ball collisions. (C) 2003 Elsevier B.V. All rights reserved.

  Abstract We investigate the crystal, magnetic and magnetocaloric properties of the Fe 5 − x Mn x Sn 3 series ( 0 ≤ x ≤ 5 ) from X-ray diffraction and DC magnetization experiments. The alloys crystallize with the lacunar Ni 2 In type of structure (P 6 3 / mmc ). The diffraction patterns of the richer Fe alloys ( x ≤ 2 ) contain tiny superstructure lines due to ordering of T atoms and vacancies within

  摘要 我们通过 X 射线衍射和直流磁化实验研究了 Fe 5 - x Mn x Sn 3 系列 ( 0 ≤ x ≤ 5 ) 的晶体、磁性和磁热特性。合金以腔隙 Ni 2 In 类型的结构 (P 6 3 / mmc ) 结晶。由于 T 原子的排序和部分填充的 2d 位置内的空位，较富的 Fe 合金 ( x ≤ 2 ) 的衍射图案包含微小的超结构线。居里温度以非单调方式降低，Mn 含量从 Fe 5 Sn 3 中的 544 K 下降到 Fe 1 Mn 4 Sn 5 中的 190 K，然后再次增加到 Mn 5 Sn 3 中的 219 K。虽然大多数合金表现为简单的铁磁体，但低场热磁化数据表明，具有中间成分 (x = 2.5 和 3) 的 Fe 5 - x Mn x Sn 3 合金经历了两个接近的类似铁磁体的转变。磁热效应是中等量级的（对于μ 0 Δ H = 2 T，~1 J kg -1 K -1 ）

  The present study describes the preparation of all five Fe-Sn intermetallic compounds, FeSn2, FeSn, Fe3Sn2, Fe5Sn3, and Fe3Sn, and the results of the X-ray diffraction study under static high pressure up to 25 GPa using nitrogen as a pressure-transmitting medium. The samples were prepared with phase purities of 97% and higher. Four Fe-Sn intermetallics, FeSn2, FeSn, Fe5Sn3, and Fe3Sn, show no phase transition to the highest pressure achieved; Fe3Sn2 undergoes two transitions to 25 GPa. The bulk moduli of these materials decrease approximately linearly with increasing Sn content, with the exception of Fe3Sn2. We also studied the solubility of Sn in alpha-Fe (alpha-Fe1-x,Sn-x). Tin expands the alpha-Fe lattice according to Vegard's law to at least 6 at.% Sn. The solid solution alpha-Fe0.92Sn0.08 was examined beyond the pressure of the alpha/epsilon-phase transition. The onset of the phase transition in alpha-Fe0.92Sn0.08 occurs at about 24 GPa, higher than the transition pressure of 14 GPa in pure alpha-Fe, but at a similar lattice parameter, a approximate to 2.800 angstrom.
