技术领域technical field
本发明属于材料制备技术领域，涉及一种高强铝合金，具体地，涉及一种激光增材制造用Al-Si-Mg-Sc-Zr铝合金粉末。The invention belongs to the technical field of material preparation, and relates to a high-strength aluminum alloy, in particular to an Al-Si-Mg-Sc-Zr aluminum alloy powder for laser additive manufacturing.
背景技术Background technique
随着轻量化、结构功能一体化的强劲需求，高强铝合金复杂精密零件在航空航天等领域应用广泛，但因其焊接性能和铸造性能差，传统加工方法难以制备出高性能、高质量的结构功能一体化构件，无法满足航空航天等领域的迫切需求。With the strong demand for light weight and integration of structure and function, high-strength aluminum alloy complex precision parts are widely used in aerospace and other fields, but due to poor welding performance and casting performance, traditional processing methods are difficult to prepare high-performance, high-quality structures Functionally integrated components cannot meet the urgent needs of aerospace and other fields.
激光选区熔化(SLM)技术是以离散/堆积的增材制造(AM)成形思想和激光焊接技术为基础，将数字化计算机辅助设计(CAD)模型切片，在二维切片内激光扫描填充，经层层堆叠后实现三维实体的成形，能够实现从三维CAD模型和金属粉末直接制备出高性能、高精度的复杂精密零件。Selective Laser Melting (SLM) technology is based on discrete/stacked additive manufacturing (AM) forming ideas and laser welding technology, slicing a digital computer-aided design (CAD) model, laser scanning filling in the two-dimensional slice, and layering After the layers are stacked, the three-dimensional solid can be formed, and high-performance and high-precision complex precision parts can be directly prepared from the three-dimensional CAD model and metal powder.
AlSi7Mg、AlSi10Mg、AlSi12等铸造铝合金粉末具有良好的流动性、易成形，目前开展激光增材制造研究和应用大多局限在上述体系的铝合金粉末，但其激光增材成形件的抗拉强度及延伸率均较低，无法达到高性能零件的使用需求。此外，2XXX、7XXX系等传统的高强铝合金粉末成形过程中易出现热裂纹，成形难度大，制约其在激光增材制造工艺上的应用。AlSi7Mg, AlSi10Mg, AlSi12 and other cast aluminum alloy powders have good fluidity and are easy to form. At present, the research and application of laser additive manufacturing are mostly limited to the aluminum alloy powders of the above systems, but the tensile strength and The elongation is low, which cannot meet the needs of high-performance parts. In addition, traditional high-strength aluminum alloy powders such as 2XXX and 7XXX series are prone to hot cracks during the forming process, and the forming is difficult, which restricts their application in the laser additive manufacturing process.
基于上述分析开发激光增材制造专用的高性能铝合金粉末至关重要。目前，国内常采用微合金化的方式提高铝合金粉末的综合性能，其中Sc、Zr、Er和Yb等合金元素可以通过自身形成析出相产生晶粒细化和强化等作用，如专利(CN 108486429)通过添加稀土铒元素、锆元素(Er：0.2～0.9％、Zr：0.05～0.5％)开发一种SLM专用AlSi7Mg铝合金粉末，从而提高了SLM成形零件的强度。本专利通过添加Sc、Zr元素实现Al-Si-Mg合金的微合金化，从而提高合金粉末的性能。Sc元素是铝合金中最为有效的微合金化元素，Sc与Al形成具有微米级的初生Al3Sc粒子和纳米级次生Al3Sc粒子，可作为有效的非均匀形核剂，起到细化晶粒的作用，同时纳米级Al3Sc粒子与基体保持共格关系，可有效钉扎位错和阻碍亚晶界运动，提高铝合金的抗拉强度和耐腐蚀性能。将Sc和Zr元素联合添加到铝合金中，Zr元素能代替Al3Sc化合物中部分Sc原子而形成Al3(Sc，Zr)复合相，复合相能保留Al3Sc的全部有益性质，而且具有更高的热稳定性。The development of high-performance aluminum alloy powders dedicated to laser additive manufacturing based on the above analysis is critical. At present, micro-alloying is often used in China to improve the comprehensive properties of aluminum alloy powder, among which alloy elements such as Sc, Zr, Er and Yb can form precipitation phases by themselves to produce grain refinement and strengthening, such as patent (CN 108486429). ) by adding rare earth erbium element, zirconium element (Er: 0.2 ~ 0.9%, Zr: 0.05 ~ 0.5%) to develop a special SLM AlSi7Mg aluminum alloy powder, thereby improving the strength of SLM formed parts. This patent realizes the micro-alloying of Al-Si-Mg alloy by adding Sc and Zr elements, thereby improving the performance of the alloy powder. Sc element is the most effective micro-alloying element in aluminum alloys. Sc and Al form primary Al 3 Sc particles with micron-scale and secondary Al 3 Sc particles in nano-scale, which can be used as an effective non-uniform nucleating agent and play a role in fine At the same time, the nano-scale Al 3 Sc particles maintain a coherent relationship with the matrix, which can effectively pin dislocations and hinder the movement of subgrain boundaries, and improve the tensile strength and corrosion resistance of aluminum alloys. When Sc and Zr elements are added to the aluminum alloy, Zr element can replace some Sc atoms in the Al 3 Sc compound to form an Al 3 (Sc, Zr) composite phase. The composite phase can retain all the beneficial properties of Al 3 Sc and has Higher thermal stability.
