摘 要: 鋁是地殼中分布最廣的金屬元素， 良好的綜合性能使鋁成為最通用的工程和建筑材料之一。 我國(guó)的鋁資源非常豐富，現(xiàn)已成為鋁及其加工產(chǎn)品的生產(chǎn)消費(fèi)大國(guó)， 產(chǎn)品質(zhì)量總體上接近國(guó)際水平。 現(xiàn)在， 世界各國(guó)都在努力減少對(duì)環(huán)境的污染， 降低能耗， 提高運(yùn)行速度， 改良使用維護(hù)條件，產(chǎn)品的輕量化是必然的發(fā)展趨勢(shì)， 鋁是首選的金屬材料， 研究開發(fā)超高強(qiáng)高韌、 高耐腐蝕、 高溫高強(qiáng)、 高彈性模量的鋁合金材料、 研究開發(fā)鋁合金復(fù)合材料和合成材料是研發(fā)主流。在提高強(qiáng)度的同時(shí)大幅度提高塑性、 韌性和綜合性能是研究的前沿， 突出進(jìn)展是工藝技術(shù)的創(chuàng)新。

Abstract:Aluminium is the most widely distributed metal elements in the earth, and has been the most universal engineering and construction materials for its excellent combined properties. China has a large aluminium deposition, and has become large country for production and consumption of aluminium and metal proccessed products, whose quality approach to those in developed countries. Up to now, all the countries are endvored to decrease pollution and energy consumption, improve working rates and maintenance of equipment, low-mass materials are always the main choice. Aluminium and its alloys will then be more widely used. The main developing trends for aluminium alloys are ligh strength high tonghness, high corrosion resistance, high temperature resistance and high modulous Al alloys, and also Al-base composites and synthesized materials. The research frontier lays in significantly improving ductility, toughness and combined properties as well as strength, and processing techniques innovation is the most important.
Key words: Al; developing trend; research frontier
