摘要
用熔体快淬继而进行晶化处理制备Sm_(20)Fe_(70)Ti_(10)试样。内禀矫顽力随淬火速率的增加而增大,其最大值为3.2(1000/4π)kA/m。综合穆斯堡尔效应和X射线衍射的方法,发现合金是由SmFe_2、SmFe_3、一种特定的顺磁相和少量Sm_3Fe_(17)相所组成的。
Sm20Fe70oTi10 samples were prepared by melt - spinning and subsequent crystallization. The intrinsic coercivity increases with the increase of quenching rate and the maximum value was 3. 2(1000/4π)kA/m. The combination of Mossbauer spectroscopy and X -ray diffaction has shown that the alloy consists of SmFe2 ,SmFe3, an undetermined paramagnetic phase and the minor phase of Sm2Fe17.
