摘要	In this work, we investigate the tensile strength and ductility of bulk Cu/Nb nanolaminates after exposure to high temperatures. We show that the interface transforms from flat to wavy at a transition temperature of 700 degrees C, and tensile strength is linearly proportional to H-1/2 (H = layer thickness). Moreover, the wavy interfaces give rise to a higher slope of the Hall-Petch law. This result can be attributed to greater resistance to slip transmission across wavy interfaces compared to planar interfaces. After 1000 degrees C for 1 h, the material still exhibits a high strength of 468 MPa and enhanced elongation. (C) 2019 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
