本文提出了一种创新的挤压技术的综合技术经济评价方法,旨在显示大塑性变形(SPD)技术的潜力。挤压技术和工艺如SPD对铝基轻质材料的性能有很大影响。因此,关于这些工艺的研究和开发可能有助于公司获得竞争优势,因为它们可以通过提供或加工具有独特特性(例如重量轻和高屈服强度)的材料而与竞争对手区分开来,从而使客户受益。因此,对于铝挤压行业的公司来说,从技术和经济的角度选择有前途的技术是非常重要的。使用集成方法,分析了选定的SPD技术。在悬臂式飞机部件的应用表明,这些技术具有技术和相当大的经济潜力:室温挤压可使屈服强度提高25%与具有类似制造成本水平的商业挤压相比,对飞机部件用户减轻重量的好处的货币评估表明,挤压具有巨大的经济潜力,室温
This paper presents an innovative methodology for integrated technical-economic evaluations of extrusion technologies and aims to show potentials of severe plastic deformation (SPD) technologies. Extrusion technologies and processes such as SPD have a strong influence on properties of aluminium-based lightweight materials. Hence, research and development regarding such processes may contribute to gain competitive advantages for companies as they can differentiate from competitors by offering or processing materials with distinctive properties (e.g. light weight and high yield strength) causing customer’s benefit. Consequently, it is of great importance for companies of the aluminium extrusion industry to select technologies that are promising from both a technical and an economic point of view. Using the integrated methodology, selected SPD technologies are analysed. The application to the use case of lever-arm-shaped aircraft components shows that these technologies bear technical as well as considerable economic potentials: extrusion at room temperature can increase yield strength by 25% compared to commercial extrusion at a similar level of manufacturing costs and the monetary appraisal of the benefits of lower weight for the users of aircraft components indicates a significant economic potential of extrusion at room temperature.
