Formation of crystal defects (B07)

项目B7研究单晶镍基高温合金中的晶体缺陷。在第三个资助期内，将解决以下方面的问题：（1）合金成分和凝固条件对铸造后热处理过程中缺陷形成和进一步微观组织演变的影响。(2)缺陷对蠕变的影响。(3)高温合金晶体镶嵌性表征新技术的进一步发展。(4)验证从薄膜组合材料库（项目B5）中获得的散装材料的微观结构结果。

Project B7 investigates crystal defects in single crystal Ni-based superalloys. In the third funding period, the following aspects will be addressed: (1) Influence of alloy compositions and solidification conditions on the formation of defects and further microstructural evolution during post-cast heat treatments. (2) Effects of defects on creep. (3) Further development of new techniques for the characterization of crystal mosaicity in superalloys. (4) Validation of microstructural results obtained from thin film combinatorial materials libraries (project B5) in bulk materials.
