摘要

在当前的研究中,讨论了对 6061 铝合金进行等沟道角轧制(ECAR)--一种严重塑性变形工艺--和人工时效热处理后的机械特性的实验研究。通过 ECAR,材料的强度提高了,但成型性却降低了。因此,这种合金的使用受到了限制。在进行 ECAR 操作后,提出了人工老化热处理工艺,并对材料的强度、硬度和可成形性进行了研究。在这方面取得了令人瞩目的成果。通过控制 ECAR 工件的时效时间和温度,不仅提高了强度,还增加了延展性。此外,还利用人工神经网络找到了最佳老化时间和温度。最后,利用神经网络给出了达到最理想机械性能的最佳老化时间和温度范围。结果表明,采用 ECAR 工艺进行受控人工时效热处理后,强度提高了 150%,成型性提高了 50%。

Strength and formability improvement of ECARed aluminum alloy 6061 sheets using the artificial aging heat treatment
In the current research, the experimental investigation of the mechanical characteristics of 6061 aluminum alloy, which was subjected to Equal Channel Angular Rolling (ECAR) – A Severe Plastic Deformation Process – and artificial aging heat treatment, has been discussed. By performing the ECAR, the strength of the material increases, but the formability will be reduced. Consequently, the usage of this alloy has been limited. The artificial aging heat treatment process has been proposed after the ECAR operation, and the strength, hardness, and formability of the material have been investigated. In this regard, remarkable results were obtained. By controlling the aging time and temperature on the ECAR piece, not only the strength increased but also the ductility increased. Moreover, an artificial neural network was used to find the optimal aging time and temperature. Finally, the best aging time and temperature ranges to achieve the most desirable mechanical properties were provided using the neural network. The result show 150% increase in strength and 50% in formability by performing controlled-artificial aging heat treatment with ECAR process.

期刊介绍: Manufacturing industries throughout the world are changing very rapidly. New concepts and methods are being developed and exploited to enable efficient and effective manufacturing. Existing manufacturing processes are being improved to meet the requirements of lean and agile manufacturing. The aim of the Journal of Engineering Manufacture is to provide a focus for these developments in engineering manufacture by publishing original papers and review papers covering technological and scientific research, developments and management implementation in manufacturing. This journal is also peer reviewed. Contributions are welcomed in the broad areas of manufacturing processes, manufacturing technology and factory automation, digital manufacturing, design and manufacturing systems including management relevant to engineering manufacture. Of particular interest at the present time would be papers concerned with digital manufacturing, metrology enabled manufacturing, smart factory, additive manufacturing and composites as well as specialist manufacturing fields like nanotechnology, sustainable & clean manufacturing and bio-manufacturing. Articles may be Research Papers, Reviews, Technical Notes, or Short Communications.
