The light-weight aluminum alloys are required for automotive materials to realize low carbon community and to protect environment of the Earth. It is also easily expected that the increasing of consumption of aluminum alloys which have high performance functions, and the controlling of nano-structure in those new aluminum alloys is really important. We have the technology of coherently controlling of nano-structure in aluminum alloys and this technique should be completed and extended for designing of new functional aluminum alloys without any expensive elements or rare earth metals. This is the purpose of this research project. It has been found out that there are specific elements which shows solubility or formation of periodicity in its metastable phase, or changing shape of equilibrium phase on some aluminum alloys. It is suggested that these behaviors introduce the changing crystal structure and precipitation sequence, or strengthening of alloys.

为实现低碳社会，保护地球环境，汽车材料需要轻质铝合金。可以预见，高性能铝合金的消费量将不断增加，而对这些新型铝合金的纳米结构控制将是非常重要的。我们已经掌握了铝合金纳米结构的相干控制技术，这一技术应该得到完善和推广，以设计不含任何昂贵元素或稀土金属的新型功能铝合金。这就是本研究项目的目的。发现某些元素在某些铝合金上表现出溶解性或在其亚稳相中形成周期性，或改变平衡相的形状。这些行为引起了合金晶体结构和沉淀顺序的变化，或合金的强化。
