Abstract Production of the intermetallic MnCo0.8Fe0.2Ge phase, interesting as magnetocaloric material, is obtained by using an almost fully amorphous mechanically alloyed precursor. Thermal treatment to develop the intermetallic phase has been reduced in time (from several hours or even days to few minutes), and temperature (from 1123 K to 723 K). Thermomagnetic measurements allow us to analyze the magnetocaloric effect and to compare the results with those obtained from conventional annealing treatments. Close relationship between magnetocaloric properties and crystal size provides further optimization of the system preserving the advantages of the production method proposed.

从机械合金化前体的低温处理中获得磁热锰（铁）锗金属间化合物

摘要 作为磁热材料的金属间化合物 MnCo0.8Fe0.2Ge 相的生产是通过使用几乎完全非晶态机械合金化前体获得的。开发金属间相的热处理时间（从几小时甚至几天到几分钟）和温度（从 1123 K 到 723 K）已经减少。热磁测量使我们能够分析磁热效应并将结果与​​从传统退火处理中获得的结果进行比较。磁热特性和晶体尺寸之间的密切关系提供了系统的进一步优化，保留了所提出的生产方法的优点。
