Abstract

The thermal–mechanical technique presented in this paper has been developed to increase the intensity and ductility of the Al-2024 alloy. As a result of standard solid solution treatment, cold rolling at room temperature, and imitation maturing at 175 °C for three hours. After aging, the Al 2024 alloy has ultimate and yield strengths at 469 MPa and 324 MPa, correspondingly. The microstructure and malleable features of an extruded Al 2024 alloying combination have been investigated in the manner of heat treatment T6. SEM, X-ray diffractometry, and optical microscopy were all used to examine the microstructure of the alloy under study. Aluminum Al 2024 alloy was established on the synthesis of rich copper intermetallic. There was a comparison of several mechanical properties since following the protrusion and heat treatment T6, researchers observed that A2024 had considerably enhanced tensile properties. Researchers found that the composite exhibits elongation of the decisive intensity and values of 381 MPa and 13.6 %, individually. An examination of the rupture exteriors of hot-squeeze-out composite specimens exposed that the malleable form of rupture predominates. Triple aging is the third aging process after the third heat treatment process, which takes place in either artificial or natural aging.

RRA Al -Cu 2024合金三次时效及其对力学性能和组织性能的影响

本文提出的热机械技术是为了提高Al-2024合金的强度和延展性而发展起来的。经过标准固溶处理，室温冷轧，175℃模拟成熟3小时。时效后，Al 2024合金的极限强度为469 MPa，屈服强度为324 MPa。采用T6热处理方法研究了挤压al2024合金组合的显微组织和可锻铸性。利用扫描电子显微镜、x射线衍射仪和光学显微镜对合金的微观组织进行了研究。在富铜金属间化合物合成的基础上建立了铝铝2024合金。通过对几种机械性能的比较，研究人员发现，经过T6的拉伸和热处理后，A2024的拉伸性能显著提高。研究人员发现，复合材料的延伸率具有决定性强度，分别为381 MPa和13.6%。对热挤压复合材料试样的断裂外观的检查表明，断裂的可锻形式占主导地位。三次时效是第三次热处理后的第三次时效过程，既可以人工时效，也可以自然时效。

期刊介绍： Egyptian Journal of Petroleum is addressed to the fields of crude oil, natural gas, energy and related subjects. Its objective is to serve as a forum for research and development covering the following areas: • Sedimentation and petroleum exploration. • Production. • Analysis and testing. • Chemistry and technology of petroleum and natural gas. • Refining and processing. • Catalysis. • Applications and petrochemicals. It also publishes original research papers and reviews in areas relating to synthetic fuels and lubricants - pollution - corrosion - alternate sources of energy - gasification, liquefaction and geology of coal - tar sands and oil shale - biomass as a source of renewable energy. To meet with these requirements the Egyptian Journal of Petroleum welcomes manuscripts and review papers reporting on the state-of-the-art in the aforementioned topics. The Egyptian Journal of Petroleum is also willing to publish the proceedings of petroleum and energy related conferences in a single volume form.
