In this paper, the morphology, distributions and sizes of precipitated phase (Mg2Si) in 6181 aluminum alloy strips manufactured by twin roll casting (TRC) process without and with electric pulse curre
The effects of grain size and texture on the corrosion properties of an Al-Cu-Mg-Si alloy were investigated.Different grain size and various crystallographic orientations were produced through a novel
Reducing localized corrosion such as inter-granular corrosion without sacrifice of strength and other good mechanical properties is an important issue for manufacturing the Al-Mg-Si-Cu alloys of high
The intergranular corrosion (IGC) behavior of 0.07Zn addicted Al-2.71Cu-1.56Li alloy and Zn-freed Al-2.78Cu-1.64Li alloy with two aging treatment systems were examined electrochemically.The influences
The Al-5.4Mg-0.5Mn-0.1Zr (wt.％) alloy was subjected to a low-temperature solution treatment at 360℃ for 6 h.As a result, nanoscale Al6Mn particles with round shape evolved.The alloy was machined into
The stress relaxation behavior of different heat-treated 7050 aluminum alloy at aging temperature has been investigated.It is observed that the phenomenon of stress relaxation is accompanied by precip
The strain localization and microstructure evolution of 2060 alloy were studied during bending.Specimens were loaded by different radii, and the microstructure evolution was studied by scanning electr
As aluminum becomes the material of choice for light weighting vehicles, the ability to manufacture complex extruded profiles with the correct mechanical properties becomes paramount.In porthole die e
Superplastie behavior of 2024 type aluminum alloy with different additions of transition metals processed by isothermal rolling at a temperature of liquid nitrogen was analyzed.Tensile tests were perf
为了提高中压电力网的规划水平,该文以最短路径和最小负荷矩法为基础,考虑物理约束、道路、支路电流和节点电压等约束条件,提出了确定主干线、连接负荷点方法、自动搜索交叉点(中间节点)以及选择导线截面的方法,给出了线路拉手前后节点和支路编号的方法,并且可以自动搜索相邻线路的联结点,实现相邻线路的手拉手连接,最终实现相邻两条自线路的自动布线.并且以农网的实际数据为例,进行计算、分析和比较,结果表明,该文提出
