| Abstract Scope |
High-pressure torsion (HPT), a method of severe plastic deformation, is a top-down technique to obtain nanostructured bulk materials at high homogeneity. In addition, alloys with an extension of their equilibrium phases beyond their compositional range, can be generated. The principal is similar to mechanical alloying, however no sintering is necessary because one obtains a bulk sample. In this study, deformation-induced mixing is induced in different binary systems. SQUID-magnetometry revealed soft magnetic properties as well as contributions of thermal relaxation and frustration, which are disentangled with AC-mode measurements. The magnetic properties are further tuned by subsequent annealing treatments. Particular emphasis in this study is placed on the correlation of magnetic data with microstructural characterization with techniques of electron microscopy, synchrotron X-ray diffraction and atom probe tomography. |
