铁磁合金作为外科植入热源被发展和使用,在癌生长中的确定位置感应生热。由于含4％(重量比)硅的镍合金在所希望的45～60℃范围有居里温度,所以被用于此研究。使用特殊的浇铸技术或浇铸、锻压后匀质过程制备热源。本文讨论了不同的处理过程对这些合金的影响,特别指出了熔炼和热处理过程中使其氧化最小的重要性,以及在近居里温度热源均匀化对相对导磁性的影响。最好的处理工艺
Ferromagnetic alloys have been developed and used as surgical implantable heat sources to induce heat generation at defined locations in the growth of cancers. Nickel alloys containing 4% by weight of silicon were used in this study since they have a Curie temperature in the range of 45 to 60 ° C desired. Use special casting techniques or casting, forging and homogenizing process to prepare heat source. This article discusses the effects of different treatments on these alloys, noting the importance of minimizing oxidation during melting and heat treatment, as well as the effect of heat homogenization at near-center temperatures on relative permeability. The best treatment process
