我国经济建设的快速发展,带动了许多行业的前进步伐。随着有色金属技术的不断发展,使铝和铝合金通过科学的进一步研究,利用先进技术改进使其在社会发展中得到广泛的应用。铝和铝合金以其自身优点与特点在航空领域、民用方面、医疗、食品包装等行业发挥着重要的作用。铝合金的密度较低,但是强度比任何材质都要高,同时又具有良好的导电性、导热性以及抗腐蚀性,在工业生产使用中的使用量紧次于钢的使用。因此,对铝合金进行热处理已经成为工业生产、热处理技术中必不可少的一部分。
The rapid development of our country’s economic construction has led to the progress of many industries. With the continuous development of non-ferrous metal technology, aluminum and aluminum alloys have been widely used in social development through further scientific research and improvement with advanced technologies. Aluminum and its alloys play an important role in the fields of aeronautics, civil affairs, medical treatment and food packaging with their own advantages and characteristics. Aluminum alloys have lower density but higher strength than any other material, as well as good conductivity, thermal conductivity and corrosion resistance. They are used less frequently in industrial production than steel. Therefore, the heat treatment of aluminum alloys has become an indispensable part of industrial production and heat treatment technology.
