现在,已经相当充分地研究了铝合金在较高温度下的持久强度和蠕变【1、2】。可是,对于铝合金在室温下的这些过程研究得很有限【3-5】。本文援引了铝合金 AM r 6(Al-Mg 系)、1201(Al-Cu-Mn 系)和1911(Al-Zn-Mg 系)的蠕变和持久强度约研究结果。合金的化学成分和机械性能见表1和表2。为了在工程计算中实际应用长期工作结构强度,所得的实验数据应当是这样地解
Now, the durability and creep of aluminum alloys at higher temperatures have been well studied [1,2]. However, there are limited studies of these processes for aluminum alloys at room temperature [3-5]. This paper cites the results of studies on creep and ultimate strength of aluminum alloy AM r 6 (Al-Mg series), 1201 (Al-Cu-Mn series) and 1911 (Al-Zn-Mg series) The chemical composition and mechanical properties of the alloys are shown in Tables 1 and 2. In order to actually apply long-term working structural strength in engineering calculations, the experimental data obtained should be such that
