摘要:

向金屬中加入纖維、顆粒、晶須等增強(qiáng)體是提高金屬復(fù)合材料力學(xué)性能的重要途徑。而現(xiàn)代工業(yè)的不斷發(fā)展對材料的多功能性提出了更高的要求。為改善材料的綜合性能，保證其在高溫、輻照等極端條件下的使用，研究人員設(shè)計(jì)了由納米級交替層組成的材料體系——納米多層金屬復(fù)合材料。由于其具有極高的界面密度，可以有效地阻礙位錯(cuò)移動(dòng)從而強(qiáng)化材料，同時(shí)促進(jìn)了輻照缺陷的吸收，有效減輕金屬的輻照損傷，在快堆、聚變堆等先進(jìn)核反應(yīng)堆中具有重要的應(yīng)用前景。近年來，納米多層金屬復(fù)合材料在國內(nèi)外得到了廣泛而深入的研究，在制備技術(shù)、結(jié)構(gòu)表征和綜合性能等研究方面取得了長足的進(jìn)步。以Cu/Nb納米多層復(fù)合材料為例，綜述了其制備技術(shù)、變形行為及熱穩(wěn)定性、抗輻照性、導(dǎo)電性等綜合性能的研究進(jìn)展，并探討了納米多層金屬復(fù)合材料的發(fā)展趨勢及應(yīng)用前景。

Abstract:

The introduction of reinforcements such as fibers, particles, and whiskers was revealed as an effective method for enhancing the mechanical properties of metal matrix composites. With the rapid development of the modern industry and science technology, higher requirements for multifunctional materials have been put forward. With aim to supply future demand from energy and national defense fields, a novel material system consisting of alternating nanoscale layers was designed and prepared, named metallic nanolamellar composites. Metallic nanolamellar composites has been a promising strategy to improve the comprehensive properties of materials, which can ensure its service life under extreme conditions such as high temperature and irradiation. Compared with traditional metal composites, metallic nanolamellar composites have very high interface density, which can effectively prevent dislocation movement and strengthen the material. In addition, the heterogeneous interface promotes the absorption and annihilation of irradiated defects, which effectively reduces the irradiation damage. Therefore, metallic nanolamellar composites are expected to become a new generation of super radiation resistant materials, and have important application prospects in advanced nuclear reactors such as fast reactor and fusion reactor. In recent years, metallic nanolamellar composites have been extensively and deeply researched, and significant progress has been made in their preparation technology, structural characterization and comprehensive performance research. Taking Cu/Nb nanolamellar composites as an example, recent research progress on preparation technology, deformation behavior, thermal stability, radiation resistance, as well as electrical conductivity of nanolaminate composites are reviewed. The development trend and application prospect of metallic nanolamellar composites are briefly discussed.
