摘要： 通过改变化学反应温度,制得了成分可表述为Fe82PxB18-x(2.4≤x≤10.1)的系列超细非晶合金微粒.当反应温度由-7℃升至28℃时,磷含量由10.1%逐渐下降至2.4%,而硼含量则由8.7%逐渐上升至13.1%.穆斯堡尔谱等实验结果表明,合金中存在Fe-P间的择优键合.

Abstract: A series of Fe-P-B ultrafine amorphous alloy power samples, which can be expressed approximately as Fe82PxB18-x(2.4≤x≤10.1), have been chemically prepared. As the reaction temperature was raised from -7 ℃ to 28 ℃, the P contents decreased gradually from 10.1% to 2.4%, while the B contents increased gradually from 8.7% to 13.1%, Mssbauer experimental results indicates that there is a preferential bonding of Fe-P to Fe-B in the samples.

Key words: Ultrafine amorphous alloy, Chemical preparation, Mssbauer spectroscopy
