Abstract Two series of FeCoNiPdx and CrxFeCoNiPd high entropy alloys were investigated using SEM-EDX, XRD technique and Mossbauer spectroscopy. Increasing of Pd content in the FeCoNiPdx samples only slightly influenced the Mossbauer spectra. They were analysed assuming simultaneous presence of hyperfine field and quadrupole splitting distributions, however random direction of observation relative to B hf and EFG caused the average QS value to be close to zero. Increasing of Cr content in the CrxFeCoNiPd samples resulted in strong decrease of the hyperfine field, its distribution becomes wide and influence of B hf , IS B hf and EFG on the Mossbauer spectra can not be separated unambiguously. The decomposing of the HEAs compositions into binary artificial Fe-dopant systems, namely [FeCoNi]-Pd and [FeCoNiPd]-Cr, allowed to interpret the magnetic structure of the two investigated series.

FeCoNiPd 和 Cr FeCoNiPd 高熵合金的穆斯堡尔研究

摘要 采用SEM-EDX、XRD和Mossbauer光谱对两个系列的FeCoNiPdx和CrxFeCoNiPd高熵合金进行了研究。FeCoNiPdx 样品中 Pd 含量的增加对 Mossbauer 光谱的影响很小。假设同时存在超精细场和四极分裂分布，对它们进行分析，但是相对于 B hf 和 EFG 的随机观察方向导致平均 QS 值接近于零。CrxFeCoNiPd 样品中 Cr 含量的增加导致超精细场的强烈下降，其分布变宽并且 B hf 、IS B hf 和 EFG 对 Mossbauer 光谱的影响不能明确分开。将 HEA 组合物分解为二元人工 Fe 掺杂剂系统，即 [FeCoNi]-Pd 和 [FeCoNiPd]-Cr，
