| 中文摘要 | Ferromagnetic Mn-Al alloy powders were fabricated by mechanical milling and heat treatment with gasatomized powders. Different processes, i.e., heat treatment before ball milling and ball milling before heat treatment, result in different microstructures and magnetic properties of the powders. It was found that H(c) increased and M(r) decreased with the size reduction regardless of the sequence of heat treatment and ball milling. However, tendency of the change in H(c) and M(r) depended on the sequence. Further annealing of the powders ball-milled after heat treatment resulted in slight decrease of H(c) and large increase of M(r). The magnetic properties, M(r) = 41.2 emu/g, H(c) = 3.1 kOe, were obtained from the powders ball-milled for 5 h after heat treatment at 650 degrees C for 20 min, and subsequent annealing at 280 degrees C for 20 min.
