一、前言铂钴合金是已被人们广泛运用的永磁材料之一,它不仅具有高的矫顽力和大的磁能积,而且有耐腐蚀,可进行塑性加工等优良性能。目前,虽然出现了稀土—钴等高磁能材料,但铂钴系合金作为永磁材料仍占据着重要位置。本工作的目的是:对等原子铂钴合金选择不同的热处理制度,用电子显微镜对试样进行薄膜透射和复型观察,并对有序相畴进行电子衍射分析,了解等原子铂钴合金的有序化过程与时效温度及磁性能之间的关系,从而找到最佳的热处理制度。
I. Introduction Platinum-cobalt alloy has been widely used by people one of the permanent magnetic materials, it not only has high coercivity and large energy product, but also corrosion-resistant, plastic processing and other excellent performance. At present, although rare earth - cobalt and other high-energy materials appear, platinum-cobalt alloy still occupies an important position as a permanent magnet material. The purpose of this work is to choose a different heat treatment system for the platinum-cobalt alloy with the same atomic weight, to observe the thin film transmission and refolding by the electron microscope, and to conduct electron diffraction analysis on the ordered phase domains to understand Ordering process and aging temperature and magnetic properties of the relationship between, so as to find the best heat treatment system.
