摘　　要：1J50软磁材料由于其良好的性能,常用作航天领域的精密元件。但是目前,1J50磁元件面临着越来越复杂极端的使用环境,这就对其提出了更严苛的要求。本文对1J50软磁材料在实验室加速高温环境下进行了试验,通过80、120、180℃的高温试验箱进行高温试验,研究其性能演化规律。结果表明,随着贮存时间的延长,1J50材料的磁性能会受到一定影响;此外,3个贮存条件下的1J50材料,在贮存时间为2~66 d时,材料磁性能衰退明显,此后,磁性能缓慢衰退。本文研究结果对于研究1J50材料在高温环境中的适应性具有一定意义。1J50 soft magnetic material is often used as precision components in aerospace field because of its goodperformance.However,at present,1J50 magnetic element is facing more and more complex and extreme use environment,which puts forward more stringent requirements.In this paper,1J50 soft magnetic material is tested in the accelerated hightemperature environment in the laboratory.The high temperature test is carried out in the high temperature test chamber at 80℃,120℃and 180℃to study its performance evolution law.The results show that with the extension of storage time,themagnetic properties of 1J50 materials will be affected to a certain extent.In addition,the magnetic properties of 1J50 materials under three storage conditions decline obviously when the storage time is 2~66 d,and then decline slowly.Theresearch results of this paper have certain significance for studying the adaptability of 1J50 material in high temperatureenvironment.
