对我国自行研制的新型高弹性合金３ＹＣ４２的不同工艺状态的组织进行了透射电镜研究。为合金设计与加工工艺的优化提供了理论与实验基础。证实了保证航天工程用特殊弹簧部件全面服役性能质量的材料设计方法的成功。
The microstructures of 3YC42, a new type of highly elastic alloy developed by ourselves, were investigated by transmission electron microscopy. It provides theoretical and experimental basis for the optimization of alloy design and processing technology. The success of material design methods that guarantee the overall service performance quality of special spring components for aerospace engineering was confirmed.
