a notable increase in shear strength of the specimens. The reason lies in the formation of diffusional joint between the interface of both Al/Cu and Cu/Ni layers at high temperature. The shear bonding...; diffusional joint 1 Introduction Severe plastic deformation (SPD) process has proven its ability as a suitable method for producing ultra-fine grained (UFG) structures in metals and alloys. The main......
J. Cent. South Univ. (2019) 26: 3103-3113 DOI: https://doi.org/10.1007/s11771-019-4239-8 Fourier-shape-based reconstruction of rock joint profile with realistic unevenness and waviness features NIE...: Rock joint shape characteristics, waviness and unevenness play essential but distinct roles in shear mechanism of rock joints. This study presents a novel method to generate virtual rock joint......
