单晶叶片大模组制备技术的研究进展
Research Progress in the Preparation Technology of Single Crystal Blades with Large Pattern Assembly
摘要
Abstract
The single crystal blade is praised as the"crown jewel",and its manufacturing technology is a key indicator of a nation's aviation industry.As the demand for aerospace equipment construction continues to rise,the need for single crystal blades has correspondingly increased each year.Consequently,large pattern assembly technology,which has the potential to significantly enhance the production efficiency of single crystal blades,has garnered increasing attention from both researchers and manufacturing entities.In this article,firstly,various forms of implementation and prospective applications of the large pattern assembly technologies are summarized,and then,the primary problems the large pattern assembly technology faced with under the condition of high-speed solidification(HRS)process,as well as coping strategies are emphetically introduced,finally,a summary and a prospect are made for the development of the preparation technology of large pattern assembly applied in the single crystal blades manufacturing in China.关键词
