摘要
本文研究了非晶粉末爆炸固结材料的磁性能。结果表明爆炸固结态样品磁性能表现为Ｂｒ／Ｂｓ、初始磁导率偏低，不易磁化到饱和，矫顽力偏高，经低温短时保温退火处理后样品磁性能显著提高，但过长的保温时间、较高的退火温度则会导致样品晶化而造成磁后退，４００℃×２０ｍｉｎ水淬为最佳退火工艺条件。
An investigation on magnetic properties of explosive consolidating amorphous powder is peiformed. The results indicate as follow: The consolidated specimen has weak magnetic properties such as low Br/Bs and μm, not easy to get saturation magnetization and high coercivity. The magnetic properties are raised obviously after short time annealing at 380℃ or 400℃. it can cause crystlization and magnetic retreat if annealing time is longer and temperature is higher. 400℃×20min and quenching by water is the best annealing process.
