摘要:
金属纳米叠层材料由于不仅可以调整其组元几何和微观结构尺度,而且可以引入具有不同本征性能的组元材料和不同结构的层间异质界面,在获得高强韧与高辐照损伤容限金属结构材料方面具有潜在的能力. 本文结合当前国内外有关金属叠层材料力学性能与辐照特性尺寸效应研究的最新进展, 分别阐述了晶体/晶体Cu/Mo与晶体/非晶Cu/Cu-Zr金属叠层材料He+辐照前后的结构演变与力学特性, 揭示了上述两类金属叠层材料的强化与损伤机制的异同, 并对纳米叠层材料研究的发展趋势进行了展望。
Abstract:
Metallic nanolaminates act as one class of typical heterogeneous materials and manifest great potential to obtain the structural materials with the combination of high strength/toughness and superior irradiation tolerance, owing to their tunable dimensional and microstructural length as well the great advantage of tunable interfacial structures. The present authors had systematically investigated the size effects on the plastic characteristics and irradiation behavior of crystalline/crystalline Cu/Mo and crystalline/amorphous Cu/Cu-Zr nanolaminates, in addition to their microstructure evolution. In this paper, the progress and the difference in the underlying strengthening mechanisms and irradiation damage mechanisms of these two kinds of metallic nanolaminates are reviewed. Finally, a brief prospect on the studies of highly irradiated tolerant nanolaminates in future is discussed.
