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具有优异机械性能的高温合金航空发动机零件的制造工艺。这一点意义重大，因为对最常用的718合金的热锻工艺进行优化，将能够有针对性地控制其纳米级沉淀组织，从而大幅提高高温强度。预期的科学成果是高温合金组织-性能关系的新物理冶金知识。预期的技术和社会成果包括提高航空发动机材料性能，创造更短的长途飞行等好处，以及更安全、更省油的航空旅行。
