论文摘要
由一种由一个铁磁性和一个dimagnetic成分组成的样品通过高压扭转在各种组合下通过高压扭转来处理热力学平衡（Co-Cu，Fe-Cu，Fe-AG）的样品。通过电子显微镜和同步X射线衍射研究接收的显微结构，显示了微结构饱和度。从微结构研究中获得的结果与磁力测定数据相关。二氧化碳样品主要显示铁磁行为，并且随着共同含量的增加而稳健性降低。发现Fe-CU样品的饱和微观结构是双相。磁性测量结果还揭示了该系统中两个不同的磁相。对于FE-AG，微结构和磁结果表明元素相之间没有混合。
Samples consisting of one ferromagnetic and one diamagnetic component which are immiscible at the thermodynamic equilibrium (Co-Cu, Fe-Cu, Fe-Ag) are processed by high-pressure torsion at various compositions. The received microstructures are investigated by electron microscopy and synchrotron X-ray diffraction, showing a microstructural saturation. Results gained from microstructural investigations are correlated to magnetometry data. The Co-Cu samples show mainly ferromagnetic behavior and a decrease in coercivity with increasing Co-content. The saturation microstructure of Fe-Cu samples is found to be dual phase. Results of magnetic measurements also revealed the occurrence of two different magnetic phases in this system. For Fe-Ag, the microstructural and magnetic results indicate that no intermixing between the elemental phases takes place.
