In 2002 Aichi steel has developed anisotropic NdFeB bonded magnets called MAGFINE25 which has the world's strongest bonded magnet with a maximum energy product of 25 MGOe. Using MAGFINE, a power seat motor used in automobile has been new designed to achieve 50% size and 40% weight reduction, and the new motor called MF motor has been launched in 2005. MAGFINE is expected to make a big progress of automobile small motor in weight reduction. In this paper, the recent progress for the anisotropic NdFeB bonded magnet MAGFINE will be reviewed about the hydrogen treatment technique, the mechanism, the new press production technique and the motor design. 相似文献

高性能汽车钢组织性能特点及未来研发方向 总被引:2,自引:1,他引:1
介绍了先进汽车用钢的组织和性能特点,认为具有较低强塑积的第一代汽车钢主要是通过铁素体、马氏体等多种基体组织的选取和配合对强度和塑性进行调控,第二代汽车钢通常具有单相奥氏体组织,表现出超高的强塑积,在汽车轻量化和安全性方面都有明显促进作用,但是其高合金质量分数提高了生产成本和难度,不利于规模化生产和应用。而第三代汽车钢则是通过在马氏体或超细晶铁素体基体上引入大量的亚稳奥氏体来提高汽车钢的强度和塑性,从而大幅度提高钢的强塑积。第三代汽车钢综合性能比第一代汽车钢提高1倍以上,其强塑积达到了25~50 GPa·%,接近或达到了第二代汽车钢的强塑积。新型合金化设计、高强度基体组织调控和大量亚稳奥氏体控制是第三代汽车钢的重要研究内容。基于轻量化与高安全性要求,低密度化与高强化将是未来第三代汽车钢的一个主要发展方向。 相似文献

The variety,inner quality and surface quality of low-alloy spring steel wire rod for domestic automobile is summarized in detail.And according to commercial low-alloy spring steel wire rod variety, product quality level and its actual application situation on automobile supplied by present industrially developed country metallurgy enterprises,it is pointed that the variety of low-alloy spring steel wire rod for domestic automobile can’t satisfy the requirements of automobile industry development,compare with overseas advanced technology,product quality has the following gaps:the first is that steel purity is low,the control level of non-metallic inclusions is not steady,there is often large grain difficult deforming non-deformation inclusions existing,the control level of steel purity has big difference,the level of large steel factory is high,but its steady has a large gap compare with foreign advanced level,not to mention small steel factory which research and development powder is low.The second is surface complete decarburization can’ t be avoided completely.The third is that surface defects are more.The fourth is that composition segregation and structure segregation are not steady,steel wire can’t be drawn normally when the segregation is serious. In all,the segregation of 55SiCrA is superior to 60Si2MnA obviously.The industrialization of domestic high level low-alloy spring steel wire rod can’t seek quick success and instant benefits,independent innovation perseveringly must be adopted,the success may be reached after master core technologies and adopt the science way of step by step. 相似文献
