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.

我们旨在为具有优越机械性能的超合金航空发动机零件设计新的制造工艺。这很重要，因为对最常用合金718的热燃烧途径的优化将能够针对其纳米级沉淀物微结构的目标控制，从而导致高温强度的大幅增加。预期的科学结果是对超合金的微观结构 - 特制关系的新物理冶金知识。预期的技术和社会成果包括增强的航空发动机材料性能，从而创造出较短的距离较短飞行，以及更安全，更省油的空中旅行。
