Abstract: front page image
(EN)The disclosed neutron shield material is configured from a boron-containing stainless steel having excellent ductility and thermal conductive properties, said steel having 0.5-2.0% B added and being based on either a austenite/ferrite biphasic stainless steel containing 3.0-10.0% Ni and 21.00-32.00% Cr, or a ferrite stainless steel containing no more than 4.0% Ni and 11.00-32.00% Cr, by volume.
(FR)L'invention concerne un matériau de blindage neutronique qui est conçu en acier inoxydable contenant du bore présentant d'excellentes propriétés de ductilité et de conductivité thermique, 0,5-2,0% B ayant été ajoutés à l'acier qui est basé sur soit de l'acier inoxydable à deux phases austénite/ferrique contenant 3,0-10,0% Ni et 21,00-32,00% Cr, ou un acier inoxydable ferrite ne contenant que 4,0% Ni et 11,00-32,00% Cr, par volume.
(JA) 中性子遮蔽材は、質量%で、B:0.5%〜2.0%が添加され、Ni:3.0〜10.0%、Cr:21.00〜32.00%を含有するオーステナイト・フェライト二相ステンレス鋼又はNi:4.0%以下、Cr:11.00〜32.00%を含有するフェライト系ステンレス鋼をベースとする、延性および熱伝導特性に優れたボロン添加ステンレス鋼で構成される。
