料が要求されるでいる。。In this way, materials containing B as a neutron absorbing material in alloys such as A1-based and Fe-based alloys have been put into practical use, but all of them have excellent absorption ability for thermal neutrons and fast neutrons. As shown in the figure, as the performance of fuel improves, thermal neutrons and fast neutrons generated in spent heating materials are increasing significantly, and materials with excellent neutron absorption ability are required more than ever. . .

本発明に係る中性子吸収能に優れた鋳造用アルミニウム
合金について、以下詳細に説明する。The aluminum alloy for casting having excellent neutron absorption ability according to the present invention will be described in detail below.
先ず、本発明に係る中性子吸収能に優れた鋳造用アルミ
ニウム合金の含有成分および成分割合について説明する
。First, the components and component ratios of the aluminum alloy for casting having excellent neutron absorption ability according to the present invention will be explained.
Ｇｄは中性子吸収能を付与するのに不可欠の重要な元素
であり、含有量が０．２ｗｔ％未満では中性子吸収能が
少なく中性子吸収材としては使用することができず、ま
た、１０ｗｔ％を越えて含有させるとＧｄの酸化が着し
くなり大気中において溶解をすることができない。よっ
て、Ｇｄ含有量は０．２〜１０ｗＬ％とする。Gd is an essential element that provides neutron absorption ability; if the content is less than 0.2 wt%, the neutron absorption ability is too low and it cannot be used as a neutron absorbing material, and if the content exceeds 10 wt% If it is contained, Gd will be easily oxidized and cannot be dissolved in the atmosphere. Therefore, the Gd content is set to 0.2 to 10 wL%.
ＢはＧｄと同じく中性子吸収能を付与する元素であり、
含有量が帆２ｗｔ％未満では中性子吸収能が少なく、中
性子吸収材として使用することができず、また、５ｗｔ
％を越えて含有させると溶湯の渦流れが悪化する。よっ
て、Ｂ含有量は０．２〜５Ｗ【％とする。Like Gd, B is an element that imparts neutron absorption ability,
If the content is less than 2 wt%, the neutron absorption capacity is low and it cannot be used as a neutron absorbing material;
If the content exceeds %, the vortex flow of the molten metal will deteriorate. Therefore, the B content is set to 0.2 to 5 W[%.
第１図および第２図に、Ｇｄ含有量お上びＢ含有量と巨
視的な中性子吸収断面積を示してあり、Ｇｄ含有量およ
びＢ含有量が増加するに従って中性子吸収能が良好とな
っており、また、Ｇｄは熱中性子に代表される低速の中
性子に対して中性子吸収断面積が優れており、また、Ｂ
は高速の中性子吸収断面積に優れていることがわかる。Figures 1 and 2 show the Gd content, B content, and macroscopic neutron absorption cross section, and the neutron absorption capacity becomes better as the Gd content and B content increase. In addition, Gd has an excellent neutron absorption cross section for slow neutrons such as thermal neutrons, and B
It can be seen that the material has an excellent high-speed neutron absorption cross section.
Ｓｉは溶湯の流動性を改善する元素であり、含有量が６
ｗｔ％未満で１キこのような効果が小さく、また、１２
ｗ【％を越えて含有されると板状の初晶Ｓｉが晶出する
ために強度が低下する。よって、Ｓｉ含有量は６〜１２
ｗｔ％とする。Si is an element that improves the fluidity of molten metal, and the content is 6
At less than 1% wt%, this effect is small, and 12%
If the content exceeds w[%], plate-like primary Si crystals will crystallize, resulting in a decrease in strength. Therefore, the Si content is 6 to 12
Let it be wt%.
Ｃｕはａ相への固溶効果により強度と高温強度を改善す
る元素であり、含有量が０．１ｗｔ％未満では強度およ
び高温強度の改善効果は認められず、また、１．０ｗｔ
％を越えて含有されると鋳造性に悪影響を及ぼすように
なる。よって、Ｃｕ含有量は０．１〜１．０ｗｔ％とす
る。Cu is an element that improves strength and high-temperature strength due to its solid solution effect in the a phase, and when the content is less than 0.1 wt%, no improvement effect on strength and high-temperature strength is observed, and when 1.0 wt%
If the content exceeds %, it will have an adverse effect on castability. Therefore, the Cu content is set to 0.1 to 1.0 wt%.
Ｍｇはａ相への固溶効果により強度を改善する元素であ
り、含有量が０，１ｗｔ％未満では強度の向上は認めら
れず、また、１．０ｗｔ％を越えて含有されると伸びが
低下する。よって、Ｍｇ含有量は０．１−１，０ｗｔ％
とする。Mg is an element that improves strength due to its solid solution effect in the a phase, and if the content is less than 0.1 wt%, no improvement in strength is observed, and if it is contained in more than 1.0 wt%, elongation is reduced. descend. Therefore, the Mg content is 0.1-1.0 wt%
shall be.
なお、Ａｌ Ｔｉ中間合金、Ａｌ−Ｔｉ−Ｂ中間合金
またはＴｉ含有フラックスを溶湯中にＴｉとして０．０
３〜０．２０ｗｔ％添加して微細化処理を行ない、マク
ロ組織を全細化して一様な組織とすることができる。In addition, if the Al Ti intermediate alloy, Al-Ti-B intermediate alloy, or Ti-containing flux is added to the molten metal, the amount of Ti is 0.0
By adding 3 to 0.20 wt % and performing a refinement treatment, the macrostructure can be completely refined into a uniform structure.
