摘要
电弧增材制造(WAAM)技术由于其在经济生产沉积率较高的大型金属组件方面的优势,在当代制造业受到越来越多的关注。高强度铝合金尤其是二系铝合金因其高比强度和优良的加工能力,而广泛应用于航空航天、军事和汽车工业。WAAM为生产大型高强度二系铝合金组件提供了一种有效的方法,并且相关领域正在迅速发展。综述了WAAM高强度二系铝合金在组织和性能、缺陷和后处理等方面的研究进展。研究结果在WAAM高强度二系铝合金的微观结构和力学性能方面是积极的。最后,在前人研究的基础上,概述了WAAM高强度二系铝合金的发展前景。
Wire-arc Additive Manufacturing(WAAM)technology has received more and more attention in contemporary manufacturing due to its advantages in the economical production of large metal components with high deposition rates.High-strength aluminum-copper alloys are widely used in the aerospace,military,and automotive industries due to their high specific strength and excellent processing capabilities.WAAM provides an effective method for the production of large,high-strength aluminum-copper alloy components,and the field is rapidly evolving.In this paper,the research progress of WAAM high-strength aluminum-copper alloy in terms of microstructure and properties,defects and post-treatment is reviewed.The results are positive in terms of the microstructure and mechanical properties of WAAM’s high-strength aluminum-copper alloys.Finally,on the basis of previous research,this paper summarizes the development prospects of WAAM high-strength aluminum-copper alloys.
