The aim of the work has been to analyze the aluminum alloys for plastic working from the point of view of their usefulness in the new hybrid manufacturing process which includes gravity casting and forging. The tests have been carried out on popular aluminum alloys from the 2xxx and 7xxx series: 2017A, 2024, 7022, and 7075, respectively. The authors have focused on the problem of using these materials at the casting stage. The analyses have included verification of the technological properties of alloys, including fluidity and the tendency to create porosities. Next, the influence of the solidification rate (associated with the use of various molds) on the casting microstructure has been determined. Based on the conducted analyzes, the alloys with the best casting behavior have been indicated. At the same time, possible problems that may occur at the forging stage have been discussed.

2XXX和7XXX系列合金作为新型铸锻混合工艺的输入材料的应用

这项工作的目的是从塑性加工铝合金在包括重力铸造和锻造在内的新型混合制造工艺中的实用性角度出发，对其进行分析。已对2xxx和7xxx系列的流行铝合金分别进行了测试：2017A，2024、7022和7075。作者集中研究了在铸造阶段使用这些材料的问题。分析包括验证合金的技术性能，包括流动性和产生孔隙的趋势。接下来，已经确定了凝固速率（与使用各种模具有关）对铸造组织的影响。根据进行的分析，已表明具有最佳铸造性能的合金。同时，
