在飞机制造商日益增长的需求的推动下，Hoogovens铝轧制品有限公司与Hoogovens Research&Development一起改进了其飞机材料的性能组合。对于这些类型的材料，已经研究了优化的加工路线以及新的合金化学成分。在保持航空航天工业要求的强度水平的同时，新的加工路线在延展性、韧性、疲劳性能以及降低大尺寸板和板材产品的残余应力方面都有重大改进。研究新合金化学的另一个目标是发展新的连接技术，如飞机结构的焊接和铜焊。与传统的航空合金相比，这些新的连接技术需要不同的性能组合。在这些改进的工艺路线和新合金开发的同时，新的超声波检测技术也被开发出来，这些技术能够预测厚板产品的疲劳性能和残余应力。(C)2000 Elsevier Science S.A.保留所有权利。
Driven by the increasing requirements from aircraft producers, Hoogovens Aluminium Rolled Products GmbH, together with Hoogovens Research & Development, has enhanced the property combinations of their aircraft materials. For these types of material, optimised processing routes as well as new alloy chemistries have been investigated. Whilst retaining the strength levels required by the aerospace industry, new processing routes offer major improvements in ductility, toughness, fatigue performance and in reduction of residual stress in large dimension plate and sheer products. A further goal of investigating new alloy chemistries is the trend towards new joining techniques such as welding and brazing for aircraft structures. These new joining techniques require different property combinations compared to the conventional aerospace alloys. In parallel to these improved processing routes and new alloy developments, new ultrasonic inspection techniques have been developed, which are able to predict fatigue performance and residual stress in thick plate products.
