We report on magnetic properties of Fe–Ni–Ti alloys after severe plastic deformation (SPD) by high-pressure torsion (HPT) and low-temperature annealing. SPD and low-temperature annealing considerably change the magnetization behavior. The main magnetic and structural characteristics of bulk and HPT materials were determined. The addition of small amounts of Ti and annealing at 300 °C will not lead to the formation of the L10 structure even with the use of the SPD technique.

严重塑性变形后掺杂 3-d 金属的 Fe-Ni 合金的磁性能

我们报告了通过高压扭转 (HPT) 和低温退火严重塑性变形 (SPD) 后 Fe-Ni-Ti 合金的磁性能。SPD 和低温退火极大地改变了磁化行为。确定了块状材料和 HPT 材料的主要磁性和结构特性。即使使用 SPD 技术，添加少量 Ti 并在 300°C 下退火也不会导致 L10 结构的形成。
