SAMULET Project 5: Processing Advanced Materials (Resubmission)

为了保持竞争力，英国航空航天工业需要确定并实施更高效、更有效的高价值零部件制造方法。由于采用了在高温下具有高强度和抗氧化性的新材料，这一任务变得更加困难。这些高性能合金虽然通过促进更高的操作温度来提高发动机性能和效率，但由于这些增强的机械性能，使得精确加工变得更加困难。当前和下一代用于发动机应用的航空航天合金的持续发展需要更高效、合适和有效的制造方法可用于其加工和制造。如果要有效地控制和使用这些过程，必须很好地描述和理解这些过程的材料科学与工程，并且我们能够有信心地预测它们对材料性能和服务行为的影响。物理理解和过程建模方面的这种进步将使制造过程中的控制更加有效，并促进整个制造过程的控制。当然，这对目前的高价值金属材料是非常有利的，但对新型航空航天材料的开发也有特别的影响，在这种材料中，材料的开发和加工能力将密切相关，以使它们能够迅速投入使用。这组项目将提供开发解决这一问题的过程所需的基础科学。通过成形、锻造工艺、金属注射成型和连接工艺的发展，将实现质量、生产率和材料利用率的进步。除了确定优化的工艺参数外，该研究计划还将同时开发新的工艺建模工具，以更好地了解该工艺并帮助未来的工艺开发。还将开发新的无损检测方法，以确保在役部件的完整性。这些技术结合在一起是必要的步骤变化，使当前一代的材料能够继续使用，并允许较新的不太了解的材料迅速进入服务，从而保持英国在这一工业部门的竞争力。通过开发新的知识管理工具和技术，产生的知识将提供给工业界。

To remain competitive the UK aerospace industry needs to identify and implement more efficient and effective methods of manufacture for high value components. This task is made more difficult by the introduction of new materials with high strength and oxidation resistance at high temperature. These high performance alloys while they increase engine performance and efficiency by facilitating higher operating temperatures are made much more difficult to process precisely as a result of these enhanced mechanical properties.The continued development of current and next generation aerospace alloys for engine applications requires that more efficient, suitable and effective methods of manufacture are available for their processing and fabrication. The Materials Science and Engineering underpinning these processes must be well characterised and understood if they are to be controlled and employed effectively and we are to be able to predict with confidence their effects on material properties and behaviour in service. Such advances in the physical understanding and process modelling will enable greater control during manufacture and facilitate greater control through the entire manufacturing process. This, of course, will be highly advantageous for present high-value metallics but will have a particular bearing on the development of novel aerospace materials where there will be a closely coupled development of material and processing capability to enable their rapid introduction to service. This group of projects will provide the basic science required to develop processes that will address this problem. Through the development of forming, and forging processes, metal injection moulding and joining processes advances in quality, productivity and material utilisation will be realised. In addition to identifying optimised process parameters the research programme will simultaneously develop new process modelling tools to create a better understanding of the process and aid process development in the future. New methods of non destructive testing will also be developed to ensure in service component integrity. These technologies taken together are the required step change to enable both the current generation of materials to find continued use and to allow newer less well understood materials to enter service quickly thus maintaining the UKs competitiveness in this industrial sector.The knowledge generated will be made available to the industrial community through the development of new knowledge management tools and techniques.
