Abstract

The article provides a brief overview of the aluminum industry development in Kazakhstan and the possibility of obtaining high-strength structural aluminum-lithium alloys. The country's enterprises produce aluminum of technical purity and aluminum alloys of low and medium strength of 6060, 6063, 6463, 6082, AK5M2, ADS-12, AD-31, AD-35, which are available materials for the construction industry. In Kazakhstan, there is progressive development of mechanical engineering which requires stronger alloys of 300-400 MPa, and for special engineering (defense, aerospace, and other advanced industries) - strengths above 415 MPa. High-strength structural aluminum alloys are based on Al-Cu-Mg, Al-Zn-Mg-Cu, Al-Li systems. Among these systems, relatively new Al-Li alloys are of great interest, having a great potential for further improvement of characteristics. The Al-Li system alloys with record-high specific strengths, corrosion-resistant, and good welded joints are widely used in the aerospace industry, where they are used for the production of power elements and housings. The article provides an overview of the known aluminum-lithium alloys, as well as the main technological stages of their production.

铝锂合金:类型、性能、应用及生产技术。概述

本文简要介绍了哈萨克斯坦铝工业的发展概况以及获得高强度结构铝锂合金的可能性。国内企业生产技术纯度铝和6060、6063、6463、6082、AK5M2、ADS-12、AD-31、AD-35中低强度铝合金，是建筑行业的可用材料。在哈萨克斯坦，机械工程的逐步发展需要300-400兆帕的更强合金，特殊工程(国防，航空航天和其他先进工业)-强度超过415兆帕。高强度结构铝合金是基于Al-Cu-Mg, Al-Zn-Mg-Cu, Al-Li体系。在这些体系中，相对较新的铝锂合金备受关注，具有进一步改善其特性的巨大潜力。Al-Li系合金具有创纪录的高比强度、耐腐蚀和良好的焊接接头，广泛应用于航空航天工业，用于生产动力元件和外壳。本文概述了已知的铝锂合金及其生产的主要技术阶段。
