Owing to hot cracking, printing aerospace grade AA7050 is challenging via fusion-based additive manufacturing. Using a deformation-based additive process, here we show that forging-like tensile properties are achieved in additively manufactured AA7050 without chemical modification for the first time (excluding lubricant on feed-rod surfaces) — YS: 430 MPa; UTS: 491 MPa; elongation: 11.2% with T74 temper.

AA7050 的增材搅拌摩擦沉积实现了类似锻造的拉伸性能

由于热裂纹，通过基于融合的增材制造打印航空航天级 AA7050 具有挑战性。使用基于变形的增材工艺，我们首次展示了增材制造的 AA7050 无需化学改性即可实现类似锻造的拉伸性能（不包括进给杆表面的润滑剂）——YS：430 MPa；耐压强度：491兆帕；伸长率：T74状态下11.2%。
