【摘要】：采用低纯度原料制备的(Fe_(74)Nb_6B_(20))_(100 x)Cr_x(x=1,3,5)非晶合金具有高的玻璃形成能力(GFA)和良好的软磁性能。铬含量的增加并未显著影响合金的玻璃化转变温度和晶化起始温度,然而其使液相线温度显著增加。(Fe_(74)Nb_6B_(20))_(100 x)Cr_x(x=1,3,5)合金的过冷液相区宽度(?Tx),Tr和γ分别为50~54 K,0.526~0.538和0.367~0.371,比未添加铬的Fe-Nb-B合金的玻璃形成能力要强。(Fe_(74)Nb_6B_(20))_(100 x)Cr_x非晶合金软磁性能优异,其饱和磁感应强度为139~161 A·m2/g,矫顽力为30.24~58.90 A/m。制备得到的Fe-Nb-B-Cr非晶合金的玻璃形成能力高、软磁性能优异且成本低廉,是一款适用于工程应用的软磁材料。
[Abstract]:The amorphous alloy has high glass-forming ability (GFAA) and good soft magnetic properties. The increase of chromium content had no significant effect on the glass transition temperature and crystallization initiation temperature of the alloy. However, the line temperature of the liquid phase has been significantly increased. This is better than the glass forming ability of Fe-Nb-B alloys without chromium. The number of the subcooled liquid zone width of the subcooled liquid zone is 5054 KV 0.5260.538 and 0.3670.371 respectively, which is stronger than that of the Fe-Nb-B alloys without chromium, and the glass forming ability of the Fe-Nb-B alloys without chromium is stronger than that of the Fe-Nb-B alloys without chromium, and the glass forming ability of the Fe-Nb-B alloys without chromium is stronger than that of the Fe-Nb-B alloys without chromium, and the glass forming ability of the Fe-Nb-B alloys without chromium is stronger than that of the Fe-Nb-B alloys with no chromium added. They are better than those of the Fe-Nb-B alloys with no chromium added, and their soft magnetic properties are better than those of the Fe-Nb-B alloys without chromium. The saturation magnetic induction intensity is 139 ~ 161A m ~ (2 / g) and the coercivity is 30.24 ~ 58.90 A / m ~ (-1). The Fe-Nb-B-Cr amorphous alloy has high glass forming ability, excellent soft magnetic properties and low cost. It is a kind of soft magnetic material suitable for engineering application.
