We aim to design a novel manufacturing process for superalloy aero-engine parts with superior mechanical properties. This is significant because optimisation of the hot-forging route of the most commonly used Alloy 718 will enable targeted control of its nanoscale precipitate microstructure leading to substantial increases in the high-temperature strength. The expected scientific outcomes are new physical metallurgy knowledge of the microstructure-property relationships of superalloys. The expected technological and societal outcomes include enhanced aero-engine material performance, creating benefits such as shorter flights over longer distances, and safer, more fuel-efficient air travel.

我们的目标是设计一种新颖的制造工艺，生产具有优异机械性能的高温合金航空发动机零件。这一点意义重大，因为优化最常用合金 718 的热锻工艺将能够有针对性地控制其纳米级沉淀物微观结构，从而大幅提高高温强度。预期的科学成果是高温合金微观结构-性能关系的新物理冶金知识。预期的技术和社会成果包括增强航空发动机材料的性能，创造诸如更长距离、更短的飞行以及更安全、更省油的航空旅行等效益。
