The binary manganese–rhodium (Mn–Rh) phase diagram was reinvestigated from 5 to 90 at.% Rh with focus on determining the transition temperature between the ordered γ′ -Mn 3 Rh and the γ -Mn phase as well as the transition temperature between of the tetragonal and cubic MnRh phase and phase boundaries, applying XRD, DTA and SEM including EDX. A reassessment of the Mn–Rh phase diagram based on obtained and literature data is given. Furthermore, the phase equilibria of the ternary bismuth–manganese–rhodium (Bi–Mn–Rh) system were experimentally investigated, focusing on the possible existence of new ferromagnetic phases. Isothermal sections at 330 °C and 600 °C were studied applying powder XRD and EDX. The corresponding phase diagram was established based on these results. No additional ferromagnetic phase was found in the ternary system.

二元Mn-Rh相图的重新评估和三元Bi-Mn-Rh体系的实验研究

二元锰-铑 (Mn-Rh) 相图从 5 到 90 at.% Rh 重新研究，重点是确定有序 γ' -Mn 3 Rh 和 γ -Mn 相之间的转变温度以及转变温度在四方和立方 MnRh 相和相边界之间，应用 XRD、DTA 和 SEM，包括 EDX。给出了基于获得的和文献数据对 Mn-Rh 相图的重新评估。此外，通过实验研究了三元铋-锰-铑 (Bi-Mn-Rh) 系统的相平衡，重点是新铁磁相的可能存在。应用粉末 XRD 和 EDX 研究了 330 °C 和 600 °C 下的等温截面。根据这些结果建立了相应的相图。在三元系统中没有发现额外的铁磁相。
