研究了熔纺Sm(FeT)₁₂合金（其中T = Ti、V、Al、Cu、Ga、Si，有些还含有少量的B和C）的磁性和结构特性。样品在淬火态下是软磁性的。在750到1050℃的温度范围内对样品进行加热时，产生了高矫顽力场。退火后，在所有合金中都发现了四方的ThMn₁₂型结构。在Sm₁₀Fe₈₀Ti₇.₅B₂.₅样品上获得了最高的矫顽力，Hc约为7.7 kOe。这些矫顽力比以前获得的要高得多，使得这些合金成为永磁体开发的良好候选材料。
The magnetic and structural properties of melt‐spun Sm(FeT)12 alloys where T=Ti,V,Al,Cu,Ga,Si and with some containing small amounts of B and C have been studied. The samples are magnetically soft in the as‐quenched state. High coercive fields are developed upon heating the samples at temperatures ranging from 750 to 1050 °C. The tetragonal ThMn12‐type structure was found in all the alloys after annealing. The highest coercivities have been obtained on a Sm10Fe80Ti7.5B2.5 sample with Hc ≂7.7 kOe. These coercivities are much higher than those obtained previously and make these alloys good candidates for permanent magnet development.
