mICROSTRUCTURE EVOLUTION AND PRECIPITATE-DISLOCATION INTERACTIONS DURING COMPLEX

超高性能铝合金的研究主题在当今具有基础性的作用。由于对高强度、低重量的先进材料的需求不断增加，这个话题在今天尤其与汽车行业息息相关。铝合金已被证明是适合在这种情况下的应用，因此，这些是最常用的铸造合金，特别是在汽车和航空航天工业。由于其各种有益的特性，它们已经超过了其他铸造合金。这些优点包括它们具有比竞争对手更高的强度重量比、更好的浇注性、更好的表面光洁度、更好的耐磨性、更好的耐腐蚀性和更好的焊接特性。

The research theme of ultra-high performance Aluminium alloys has a fundamental role nowadays. This topic is of extremely relevance today particularly in automotive since the increasing demand for advanced materials with high strength and low weight. Aluminium alloys have been proved to be suitable for the applications in such circumstances, therefore these are the most commonly used of the casting alloys especially in the automotive and aerospace industries. They have overtaken other foundry alloys as a result of their various beneficial attributes. These include their ability to give a high strength to weigh ratio, better castability, better surface finish, better wear resistance, better corrosion resistance and better welding characteristics than their competitors.
