    摘要:

    用于核反應(yīng)堆的新候選材料研發(fā)是一項重要任務(wù)。由于反應(yīng)堆環(huán)境惡劣，堆芯材料在高溫下應(yīng)具有良好的綜合性能，如良好的強度、延展性、耐腐蝕性能和耐輻照性能等。此外，還應(yīng)考慮低中子吸收橫截面和中子活化。典型的空間核反應(yīng)堆核心材料的選擇主要由工作溫度決定。隨著反應(yīng)堆設(shè)計工作溫度的升高，一般以316不銹鋼、鎳基高溫合金、氧化物分散強化（ODS）鋼、鈮合金、難熔金屬和SiC陶瓷的順序來選擇設(shè)計堆芯材料。此外，高熵合金已經(jīng)引起核領(lǐng)域的廣泛關(guān)注。本文綜述了以上不同材料體系在輻照過程中的力學(xué)性能演變，為進一步提升抗輻照性能提供研究指導(dǎo)。

    Abstract:

    Developing novel materials for nuclear reactors is a crucial research task. Due to the harsh conditions in the reactors, core materials must possess exceptional high-temperature properties, including high strength, ductility, corrosion resistance, and irradiation resistance. Additionally, the low neutron absorption cross-section and the neutron activation are also important considerations. It is widely acknowledged that the choice of core material for a typical space nuclear reactor is primarily determined by the operation temperature. Generally, with increasing the designed operation temperature of reactor, 316 stainless steel, nickel-based superalloys, oxide-dispersion-strengthened (ODS) steel, refractory metals, and SiC ceramics are preferred in order. Besides, the high entropy alloys attract extensive attention for nuclear applications. This review summaries the evolution of mechanical properties of different material systems during irradiation process, providing guidance for the further research in irradiation resistance.
