一、前言近代机器制造中,大量采用了铝合金,展望将来,铝合金的应用将更广泛。机器结构中所采用的铝合会,主要是能形成固溶体的铝合金;而使铝合金加强的方法主要是靠时效处理来使固溶体产生转变。但是,铝合金的时效理论,或认为非常复杂,难于捉摸,或沿用美国 W.L.费克(W.L.Fink)和 D.W.史密斯(D.W.Smith)的不正确的理论,因而在生产上和研究工作中缺乏了正确的指导方向。本文内将苏联科学家对 First, the foreword In modern machinery manufacturing, extensive use of aluminum, the future, the application of aluminum alloys will be more extensive. The aluminum alloy used in the structure of the machine is mainly an aluminum alloy capable of forming a solid solution; and the method of strengthening the aluminum alloy is mainly the transformation of the solid solution by aging treatment. However, the theory of aging of aluminum alloys, or considered to be very complicated and elusive, or following the incorrect theories of WLFink and DW Smith in the United States, lacks correctness in production and research work The guiding direction. This article will be Soviet scientists
