A study was made of the optimum composition of 2-17 type Sm(Co, Cu, Fe,Zr)_z magnets. It shows that Sm content is about 27 wt%, instead of 25.5 wt% reported by Ojima. It is shown that the liguid phase sintering process, quite other than a simple solid phase sintering, is favourable to control and to adjust exactly their compositions, to play fully the active role in step aging treatment, to enhance strongly the coercivity and the energy product and to prepare successfully magnets with excellent properties....

实验表明,Sm(Co,Cu,Fe,Zr)_Z 2-17磁体的最佳成份区与Ojima所报道的不同,Sm含量不是25.5%而是27.0—27.5wt%。而且简单的固相烧结难以获得优异性能。采用液相烧结工艺,有利于准确调整和控制成分,有效地发挥多级时效处理的有利作用,显著地增强矫顽力和能积,可稳定地进行大批量制备高性能磁体。最高性能可达30.5 MGs·Oe。

Experimental results showed that the crystalline structure of the ingot is different with different cooling rates. In the equi-axed grain structure, the inner of the grain is deficient in Cu; free Cu concentrates on the grain boundaries, where an amount of high temperature phase of hexagonal structure of Sm_2Co_(17-x)T_x is preserved, resulting in a decrease...

Effects of the as-cast crystaline structure and segregation in Cu on the coercivity of Sm(Co, Cu, Fe, Mn)_(7.8) permanent magnets have been investigated. Experimental results showed that the crystalline structure of the ingot is different with different cooling rates. In the equi-axed grain structure, the inner of the grain is deficient in Cu; free Cu concentrates on the grain boundaries, where an amount of high temperature phase of hexagonal structure of Sm_2Co_(17-x)T_x is preserved, resulting in a decrease in the coercivity. In the fine-columnar grain structure, no serious segregation in composition has been observed. Magnets after sintering and solution treatment exhibit the cellular microstructure; precipitated Cu and SmCo_(5-x)T_x phase rich in Cu disperse on the cell-wall. They probably play, in the course of magnetization reversal, the role of pinning the domain wall, hence, giving high coercivity.

本文研究了Sm(Co, Cu, Fe, Mn)_(7.8)永磁体铸造结晶组织及Cu偏析对矫顽力的影响。结果表明,不同冷却速度的铸造合金锭具有不同的结晶组织。在等轴晶组织中,晶内贫Cu,晶界上富集游离Cu,保存有一些Sm_2Co_(17-x)T_x六方结构高温相,造成矫顽力下降;而在细的柱状晶组织中,无严重的成分偏析。经烧结和固溶处理后的磁体,为位错胞状显微组织,胞壁间弥散着脱溶Cu和富Cu的SmCo_(5-x)T_x相,它们在反磁化过程中,可能对畴壁起着钉扎作用,因而具有高矫顽力。
