摘要
为解决聚变堆低温超导异型支撑壁厚尺寸不均匀、材料变形抗力较大、锻造温度范围窄、工装模具多、操作配合难度大等问题。本文对其锻造成形进行有限元分析,预测了不同锻造工艺及模具下其金属流动规律及关键受力部位的尺寸。基于分析结果进行了相关试验。其中锻造工艺试验结果表明,最终尺寸完全满足要求,圆角处材料取样测试结果表明,该处微观组织及常温、极低温下力学性能优异。
In order to solve the problems of uneven wall thickness and size, large deformation resistance of materials, narrow forging temperature range, many tooling dies, and difficult operation & coordination of low-temperature superconducting special-shaped support of fusion reactors, the finite element analysis of its forging forming has been carried out and the metal flow law and the size of the key stress parts under different forging processes and dies have been predicted in the text. The relevant experiments have been carried out on the basis of the analysis results. Among them, the forging process test results show that the final size fully meets the requirements, and the material sampling test at the fillet results show that the microstructure and mechanical properties at room temperature and extremely low temperature are excellent.
