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. |
