The magnetic properties and impact toughness were measured and the fracture surfaces were observed by sem 分别测试磁体磁性能和冲击韧性,并采用扫描电镜观察磁体断口微观形貌。
The result showed that after adding grain refiner , the hardness of magnesium alloys changed little while the impact toughness increased 结果表明，添加细化剂后，镁合金的硬度变化不大，而冲击韧性提高。
The impact toughness could be prominently improved by ag mainly because of the depressing of grain growth during the sintering , and some granuliform nd - rich phase appeared Ag元素提高磁体冲击韧性主要是因为细化了主相晶粒并使颗粒状富nd相增多。
The results shows that the failure parts has high silicon content and uneven hardness , the impact toughness and elongation is far below the specification of the material 结果发现，失效件的硅含量偏高、硬度值很不均匀，冲击韧度和伸长率远低于材质要求，因而导致脆断。
It follows that the fracture behaviour and the impact toughness and magnetic properties , especially the coercivity , were dramaticly different according to the ways elements addition 结果表明,不同合金元素或不同添加方式,对磁体断裂方式、冲击韧性及磁性能(特别是矫顽力)有不同的影响。
After chemical and physical test , on conveyor chain material , it is concluded that the composition and various mechanical properties can meet the standard , except impact toughness at room temperature 摘要对圆环链母材进行理化检测，证明化学成分和各项力学性能指标均符合要求，只有常温冲击韧性不符合要求。
The impact toughness of the magnets with 0 . 05 % ag was 70 % higher than that of commercial n35 magnets without magnetic properties deterioration . and there was no visible changes to fracture behaviour of these magnets 添加0 . 05 % ag磁体冲击韧性较普通商业n35磁体提高70 % ,同时磁性能几乎没有降低,并且该成分磁体断裂方式没有明显改变。
The impact toughness of the magnets could be improve with appropriate alloying elements addition during ball milling while there was no visible changes to the fracture behaviour , and the coercivity of magnets with al and ti was significantly enhanced 晶间单独或复合添加适量合金元素对磁体冲击韧性均有一定提高作用,但对断裂模式没有明显影响,复合添加ti 、 al能显著提高磁体矫顽力。
Ep epoxy powder coating are thermosetting powder coating based on epoxy resin , with modified of diversiform curing agent , and are characterized of anti corrosive , excellent impact toughness , and used in pipeline corrosion protection , family fitting etc Ep粉末涂料是一种以环氧树脂与多种固化剂改性而成的热固性粉末涂料，具有较好的耐化学腐蚀性，极佳的冲击韧性，广泛应用于重防腐的管道，家庭用具等领域。
The impact toughness of the magnets with al and ti during melting could be prominently improve , and the fracture behaviour of the magnets was visibly changed , but the coercivity of magnets depended on the proportion of al and ti 熔炼复合添加ti 、 al明显提高磁体冲击韧性,并且对磁体断裂模式影响较大,矫顽力随ti 、 al的添加比例出现较大波动。熔炼合金化的nd15 . 5fe76 . 5al1ti0 . 5b6 . 5磁体冲击韧性较商业n35磁体提高了51 . 8 % ,磁性能略有下降。
