摘要
织构广泛存在于铝合金制品中,并影响着材料的一系列性能,包括强度、延展性、成形性和腐蚀性等。介绍了目前织构的一般测试分析方法,主要阐述了铝合金制造加工过程中产生的各种类型织构,如铸造织构、变形织构和再结晶织构等以及它们的演变规律,分析了铝合金加工工艺对材料最终的织构成分及织构强弱的影响,并揭示了厚板铝合金轧制和铝合金的搅拌摩擦焊接过程中产生的不均匀分布织构,以及其对材料性能的影响。最后介绍了铝合金织构的应用情况,并对铝合金织构的研究前景进行了展望,提出了在线织构检测技术,将是未来铝合金织构测试分析的主要发展方向之一。
Texture widely exists in aluminum alloy products. It affects a series of properties of the material, including strength, ductility, formability and corrosion resistance, etc. In this paper, the general measuring methods of texture were introduced. Texture generated in the manufacturing of aluminum alloy such as casting texture, deformation texture and recrystallization texture, as well as their evolution were reviewed and analyzed. The processing influence on the component and intensity of final texture in aluminum alloy was analyzed. The uneven distribution of texture in thick aluminum alloy plates and friction stir welding joints, as well as its influence on the material performance were revealed. Finally, the applications and research prospect of aluminum alloy texture were outlined. It was proposed that online texture detection technology will be one of the main research directions in future research of aluminum alloy texture.
