EFFECT OF NANOCRYSTALLINE AND TWIN BOUNDARIES ON CORROSION BEHAVIOR OF 316L STAINLESS STEEL USING SMAT A.Q. Lü1,Y. Li3,G. Liu4,C.M. Liu1,Y. Zhang1,Q.H. Zang2 (1.School of Materials and Metallurgy... to the appearance of twin boundaries and the obvious reduction in corrosion resistance attributed to the presence of nanocrystaline boundaries. Key words:surface mechanical attrition treatment; 316L stainless......
Limited Effect of Twin Boundaries on Radiation DamageJin Gao,Zhi-Jun Liu,Fa-Rong WanDepartment of Materials Physics and Chemistry,School of Materials Science and Engineering,University of Science...,the distribution of the cavities varied near the general grain boundary and the twin boundary.Cavities-depleted zone was readily observed near the general grain boundaries,which was rarely observed near the twin......
Effect of grain size on fatigue cracking at twin boundaries in a CoCrFeMnNi high-entropy alloyA.G.Wang1,X.H.An1,J.Gu2,X.G.Wang3,L.L.Li3,4,W.L.Li1,M.Song2,Q.Q.Duan3,Z.F.Zhang3,X.Z.Liao11.

, and the fraction of the twin boundaries showed a pronounced increase. Analysis of the twin crystallographic nature of the FCC crystals showed that four kinds of twin variants can be formed within austenite... with the migration of the large-angle grain boundaries. JIN et al [19] studied the effect of the heat treatment process parameters on the annealing twin formation in 304L austenitic stainless steel by applying......
Atomic-resolution studies on reactions between basal dislocations and {10■2} coherent twin boundaries in a Mg alloyHuhu Su1,Xinzhe Zhou1,Shijian Zheng2,Hengqiang Ye1,3,Zhiqing Yang11. Shenyang...} coherent twin boundaries(CTBs) in a Mg alloy were studied with atomic resolution. Individual dislocation-CTB reactions produced steps with residual dislocations and multiple t winnin g dislocations(TDs......

Twin boundary: Controllable interface to fatigue crackingZhefeng Zhang,Linlin Li,Zhenjun Zhang,Peng ZhangShenyang National Laboratory for Materials Science, Institute of Metal Research, Chinese Academy of Sciences摘 要:Twin boundaries(TBs) are key factors influencing the mechanical properties of crystalline materials. We have investigated the intrinsic......
and energetics of coherent twin boundaries (CTBs) and glide twin boundaries (GTBs) in hexagonal close-packed (hcp) Ti. The formation mechanism of GTBs and their correlation with twin growth were... of single-layer twinning disconnections. The pile-up of twinning disconnections should be responsible for the wide steps at twin boundaries as observed in high-resolution transmission electron......
twin grain boundaries are investigated, using electron energy loss spectroscopy (EELS) and energy dispersive X-ray spectroscopy (EDXS). The measurability of electronic structures of the twin grain...Spatially Resolved Analytical Electron Microscopy at Grain Boundaries of α-Al2O3S.Nufer, A.G.Marinopoulos, C.Elsasser, W.Kurtz and M.RuhleMax-Planck-Institut fur Metallforschung, Seestr. 92, D-70174......
