摘要：
Compositionally graded microtruss cellular materials can be created by electrodepositing ultrahigh-strength sleeves of nanocrystalline material over precursor microtruss cores. Due to their position relative to the neutral axis of the struts, even relatively thin coatings can provide significant strength and weight benefits to the precursor assembly. Using nanocrystalline nickel as an example, the questions of strength prediction, performance increase, sleeve/core delamination and sleeve fracture are discussed. (C) 2012 Acta Materialia Inc.
