超重力定向凝固是一种有潜力的改善合金力学性能的技术。在足够高的离心加速度下，熔体从层流状态转 变为湍流，然后再恢复为层流状态，这势必显著影响凝固前沿的稳定性，从而影响合金的微观结构和力学性能。 为了在 离心超重力方向上建立一个可控的温度梯度，将多区温度调节系统与坩埚底部的氩气冷却系统相结合，研发了一种超 重力定向凝固炉，并在1g和535g条件下进行测试，验证了超重力定向凝固熔铸炉设计方案的可行性。实现了在超重力 环境下对于温度梯度和冷却速率的调控。力学性能结果表明，535g样品的力学性能显著优于1g样品，抗拉强度提高了 约18%，伸长率约提升76%。证实其在优化合金微观结构及提升力学性能方面的显著优势，为高性能材料制备提供了新 方法。

Hypergravity-assisted directional solidification is a promising technique for enhancing the mechanical properties of alloys. Under sufficiently high centrifugal-induced hypergravity acceleration, the melt undergoes a transition from laminar to turbulent flow before reverting to laminar flow, significantly affecting the thermal stability of the solidification front and, consequently, the microstructural evolution and mechanical performance of the alloy. To establish a controllable temperature gradient along the direction of centrifugal hypergravity, a multizone temperature regulation system was combined with an argon gas cooling system at the bottom of the crucible. A hypergravity directional solidification furnace was developed and experimentally evaluated, with tests conducted under 1g and 535g conditions to verify the feasibility of the proposed design for the hypergravity directional solidification casting furnace. By coupling the multizone temperature control method with the crucible bottom cooling method, control over the temperature gradient and cooling rate was achieved under hypergravity conditions. The mechanical property results of the samples indicate that the 535g sample exhibits significantly superior mechanical properties compared with those of the 1g sample, with the tensile strength increasing by approximately 18% and elongation improving by approximately 76%. These results validate the feasibility and effectiveness of the proposed system, demonstrating its significant advantages in refining solidified structures, optimizing alloy microstructures, and enhancing mechanical properties, thereby providing a novel approach for the preparation of high-performance materials.
