研究了低温碾磨诱导的非均相镁基纳米复合材料（5 vol % SiC纳米复合材料）的微观结构演变。随着铣削时间的延长，纳米复合材料的强度和延展性/韧性同时提高，打破了镁基复合材料强度和韧性之间的矛盾。晶粒取向和片状软区厚度影响合金的强度和延展性/韧性。结果表明，独特的非均相结构设计是制备高性能镁基纳米复合材料的有效途径。(C) 2020 Elsevier B.V.版权所有
The cryomilling induced microstructure evolution of the heterogeneous Mg-based nanocomposites (5 vol % SiC nanocomposites) was investigated. The strength and malleability/toughness of nanocomposites were increased simultaneously due to the optimized microstructure when extending the milling time, and it broke the conflicts between strength and toughness in Mg-based composites. The strength and malleability/toughness were affected by the crystalline orientation and the thickness of flake-like soft region. It demonstrated the unique heterogeneous structure design is an attractive approach to synthesize high performance Mg-based nanocomposites. (C) 2020 Elsevier B.V. All rights reserved.
