The stability of SmCo_5 permanent magnet prepared by liquid phase sintering

液相烧结SmCo_5永磁体热稳定性与磁体的内禀矫顽力H_(ci)及磁滞回线方形度H_k发现有密切关系,找到了初始的不可逆磁损失、长期时效过程中的不可逆磁损失及在较高温度(如250℃)下的总损失(可逆与不可逆损失的和)与H_(ci),H_k的关系曲线。为改善磁体的热稳定性,必须提高磁体的内禀矫顽力及磁滞回线方形度。

The effect of post-sintering heat treatment on the mechanical properties of a liquid phase sintered tungsten-base ahoy (95W-3.SNi-1.5Fe) has been investigated. Through heat treating in vacuum at 1200℃, the hydrogen content of the alloy was decreased by 70%, however, its strength was increased by 30%, and its ductility and fracture toughness were also improved. A SEM observation on the fracture surface of the alloy showed that interfacial failures occurred at the tungsten particle-matrix interface in specimens...

The effect of post-sintering heat treatment on the mechanical properties of a liquid phase sintered tungsten-base ahoy (95W-3.SNi-1.5Fe) has been investigated. Through heat treating in vacuum at 1200℃, the hydrogen content of the alloy was decreased by 70%, however, its strength was increased by 30%, and its ductility and fracture toughness were also improved. A SEM observation on the fracture surface of the alloy showed that interfacial failures occurred at the tungsten particle-matrix interface in specimens with higher hydrogen content. While in specimens with lower hydrogen content, the fracture mode were transfered from interfacial to interfacial plus partly cleavage failures in tungsten particles. It appears that the hydrogen brittleness is diminished, and the cohesion of the interfaces increased, as a result of decreasing the hydrogen content of the alloy. Ion microprobe analysis showed that in specimens with higher hydrogen content, hydrogen is concentrated at interfaces, which further accounts for the influence of hydrogen on the interracial failure of the alloy.

研究了液相烧结钨基高比重合金(95W-3.5Nj-1.5Fe)烧结后热处理对力学性能的影响.经过1200℃真空热处理,合金中氢含量降低了70%,强度提高约30%,延性显著增加,同时断裂韧性值也有提高。通过扫描电镜断口金相观察,发现氢含量高的试样显示了基体-钨颗粒相界面断裂,对氢含量低的试样,断口微观形态由沿相界面断裂方式过渡到相界面断裂和部分钨颗粒解理断裂方式,说明削弱了氢脆,加强了相界面结合力,从而改善了合金的力学性能。对氢含量高的试样,作了离子探针分析,其结果指出钨颗粒周围含氢最较高,相界面有氢的富集,它是导致相界面断裂的根源。

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....

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. The highest valuc of energy product, 30.5 MGs·Oe, has been obtained.

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。
