变形高温合金及其制备工艺研究进展
Research progress of wrought superalloys and preparation processing
摘要
Abstract
This paper reviews the research work carried out by the research group on wrought superalloys and their preparation processes over the past more than ten years.On one hand,regarding wrought superalloys for aerospace applications,including high-strength hard-to-deform superalloys serving above 750℃,a new generation of low-expansion superalloys with both structural and functional properties,and wrought superalloys for high-strength fasteners at elevated temperatures,the microstructural characteristics and typical properties of these new materials are elaborated.On the other hand,in terms of wrought superalloys for nuclear reactors,the research progress and microstructural and performance characteristics of corrosion-resistant and irradiation-resistant high-temperature nuclear structural materials are introduced.Meanwhile,the research progress of advanced technologies such as the hot extrusion cogging process for fine-grained and homogeneous wrought superalloy bars and the hot extrusion forming process for hollow thin-walled long shaft forgings is presented.Finally,the research and development of wrought superalloys,process technology advancement,and industrial prospects in China are prospected:(1)establish an independent forward research and development system;(2)break through the full-process stable preparation technology;(3)expand cross-domain applications;(4)promote the large-scale recycling of returned materials.关键词
