AI Technical Summary

Technical Problem

Existing neutron absorbing materials containing B and Gd suffer from high cost and poor ductility, making it difficult to prepare high-strength and high-toughness aluminum-based neutron absorbing materials.

Method used

A uniformly structured gadolinium/copper/magnesium/manganese/aluminum neutron absorber was prepared by using an ultrasonic-assisted liquid-phase composite method to introduce Gd and Mn elements into pure aluminum melt through Al-Gd and Al-Mn master alloys and then hot rolling.

Benefits of technology

This research has resulted in a low-cost, high-strength, and highly ductile neutron-absorbing material that avoids B4C particle aggregation and stress concentration, thereby improving the material's processability and neutron absorption performance.

Abstract

本发明提供了一种易变形钆 / 铜 / 镁 / 锰 / 铝中子吸收材料及其制备方法，将金属Mn加入至纯铝溶体中，并辅以超声搅拌处理，制备得到Al‑Mn中间合金；将金属Gd加入至纯铝熔体中，并辅以超声搅拌处理，制备得到Al‑Gd中间合金；将纯Al，纯Cu、Al‑Mn中间合金和Al‑Gd中间合金混合熔化，熔化后再添加纯Mg，使其完全熔化，熔化过程中辅以超声搅拌处理分散合金元素，得到组织均匀的钆 / 铜 / 镁 / 锰 / 铝中子吸收材料铸锭，随后进行热轧处理，得到易变形钆 / 铜 / 镁 / 锰 / 铝中子吸收材料。本发明通过调整含钆铝合金中不同合金元素的含量，采用超声辅助液相复合法实现组织均匀的含钆铝合金的快速制备，并辅以轧制得到兼具强度，刚度，塑性及中子吸收性能的中子吸收材料。
