可强化铝合金,如硬铝、锻铝及超硬铝合金,经过淬火、人工时效处理,强度有显著的提高,室温抗拉强度可达44～54kg/mm~2。但在机械加工后或在放置过程中发生变形。为了应付使用必须将零件校正后立刻装配。为此,我们进行了一系列的试验和生产实践,对高强度变形铝合金机械加工后变形的特点、变形的原因进行了探索,并制定了一套行之有效的冷锻工艺,基本上解决了高 Can be strengthened aluminum, such as duralumin, forged aluminum and super-hard aluminum alloy, after quenching, artificial aging treatment, the strength has been significantly improved, room temperature tensile strength up to 44 ~ 54kg / mm ~ 2. However, deformation occurs after machining or during placement. In order to cope with the use of components must be corrected immediately after the assembly. To this end, we conducted a series of tests and production practices, the deformation of high-strength deformation of aluminum alloy machining characteristics, the reasons for the deformation were explored, and developed a set of effective cold forging process, basically solved High
