蠕变时效成形技术是利用金属的蠕变特性,将成形与时效热处理同步进行的一种成形方法。文章从蠕变时效成形基本原理以及成形特点出发,重点阐述了基于零件回弹补偿的工装外型面的优化技术、成形工装、蠕变时效成形过程对零件材料微观组织性能的影响和新型可时效成形铝合金的开发及应用等关键技术的研究进展及发展趋势,并针对我国大飞机的研制需求,结合国内现有研究基础和水平,提出了我国开展蠕变时效成形技术研究的建议。
Abstract：Creep age forming(CAF) is a combined forming and ageing heat treatment process.Starting from the principle and the characteristics of the creep age forming process,the research situation and the developing tendency on the key technologies,such as tool surface optimisation based on the springback,forming tools,the effect of the creep age forming on mechnical properties and microstructural evolution,development of novel damage tolerant alloys are detailed introduced in this paper.Finally,based on the existing research situation and the requirements for developing the large airplane in China,some suggestions and research emphasis on developing creep age forming technologies are pointed out.
