摘要
锆合金由于其优良的抗腐蚀能力和低的热中子吸收截面被广泛应用于核能领域,但是目前针对锆合金的塑性加工性能研究较少,这限制了锆合金的使用场合和使用范围。本文基于数值模拟和实验研究了锆合金板材上微孔的压印成型过程,分析了锆合金板材上微孔的成型特点及材料塑性流动变化情况,探讨了锆合金板材上微孔成型规律。结果表明利用压印成型技术可有效的在锆合金板材上加工制备出满足要求的微孔,这对锆合金板材的进一步利用具有重要的意义。
Zirconium alloys are widely used in the field of nuclear energy due to its excellent corrosion resistance and low thermal neutron absorption cross-section.However,there are few studies on the plastic processing properties of zirconium alloys,which limits the application occasions and scope of zirconium alloys.Based on the numerical simulation and experiment,the coining process of microporous on zirconium alloy sheet was studied in this paper.The forming characteristics of microporous on zirconium alloy sheet and the change of material plastic flow are analyzed,and the forming law of microporous on zirconium alloy sheet was discussed.The results show that the coining technology can effectively process the microporous that meet the requirements on the zirconium alloy sheet,which is of great significance to the further utilization of the zirconium alloy sheet.
