摘要:

為了滿足飛機不同部位對結(jié)構(gòu)材料服役性能的苛刻要求，面對被復(fù)合材料等其他結(jié)構(gòu)材料替代的激烈競爭局面，鋁合金材料不斷發(fā)展新的合金及其材料的加工技術(shù)，設(shè)法提高其綜合性能及其均勻性，發(fā)展大規(guī)格材料及材料/構(gòu)件一體化加工原理與技術(shù)。簡介了飛機的發(fā)展對鋁合金高綜合性能及大規(guī)格材料的要求，闡述了航空鋁合金材料由單一高靜強度向高強高韌耐蝕抗疲勞高綜合性能以及向大型規(guī)格發(fā)展的狀況，概述了適應(yīng)飛機發(fā)展的高性能鋁合金材料的成分、組織與性能關(guān)系的相應(yīng)調(diào)控原理與技術(shù)，并對高強鋁合金厚板加工的一些創(chuàng)新技術(shù)關(guān)鍵進(jìn)行了簡要介紹、分析與討論。

Abstract:

In order to meet the strict requirements of various components of airplane on the service performance of the �゛luminum�� alloys materials which are faced with the fierce substitution competition with composites and other structural materials, scientists and engineers in aluminum alloys need to keep developing new alloys and the processing technology of their materials, try to improve the comprehensive performance and its uniformity, develop the processing principle and technology of large specification products, and material/structural parts integration. This paper briefly introduces the demand of airplane development on the high comprehensive properties and large specification products of hard aluminum alloys, elaborates the development of the aerocraft aluminum alloys from high static strength to high strength, toughness, corrosion and fatigue resistance, and high comprehensive properties, as well as the aerospace structures from riveted jointing and welding to processing of super�瞭hickness plates, large�瞫ize forgings and integral structural parts; generally explain the correspondent adjustment principle and technology on the relationship among compositions, microstructures and properties of the hard aluminum alloys materials suitable for the airplane development; as well as briefly introduces, analyzes and discusses on some innovative technology keys for processing of the super�瞭hickness plates of hard aluminum alloys.
