主要讨论一些材料纳米结构如何影响其性能。重点是铝合金中的晶粒细化剂及第二相、消光非晶态磁性铁合金、磁性多层储媒及读/写设备以及单壁碳纳米管的一维晶体。 铝合金中的晶粒细化剂 锻制铝合金应用于饮料罐、平版印刷片及汽车仪表盘等。在铸造过程中，初始铝晶粒尺寸要小 Discuss how some materials nanostructures affect their performance. The emphasis is on grain refiners in aluminum alloys and second-phase, ductile amorphous ferromagnetic alloys, magnetic multi-layer media and read / write devices, and single-dimensional crystals of single-walled carbon nanotubes. Grain refiner in aluminum alloy forged aluminum alloy used in beverage cans, offset printing plates and car dashboards. During casting, the initial aluminum grain size is smaller
