Dual effect of Cu on the Al3Sc nanoprecipitate coarsening被引量：4
《Journal of Materials Science & Technology》2020年第2期38-45,共8页Y.H.Gao L.F.Cao J.Kuang J.Y.Zhang G.Liu J.Sun 
financially supported by the National Natural Science Foundation of China(Nos.51621063,51625103,51722104,51790482,51761135031 and 51871033);the National Key Research and Development Program of China(No.2016YFB0700403);the 111 Project of China(No.BP2018008);supported by the International Joint Laboratory for Micro/Nano Manufacturing and Measurement Technologies.
It is generally considered that the Al3Sc nanoprecipitates are highly thermal stable,mainly due to quite slow Sc diffusion in theα-Al matrix.In this paper,we demonstrate in an Al-Cu-Sc alloy that the Cu atoms have du...

Chemical structure of grain-boundary layer in SrTiO_3 and its segregation-induced transition: A continuum interface approach被引量：3
《Chinese Physics B》2018年第6期3-12,共10页Hui Gu 
supported by the National Natural Science Foundation of China(Grant No.51532006);the Fund from Shanghai Municipal Science and Technology Commission(Grant No.16DZ2260600);the 111 Project of the Ministry of Education;the Fund from the National Bureau of Foreign Experts(Project No.D16002)
Grain-boundary（GB） structures are commonly imaged as discrete atomic columns, yet the chemical modifications are gradual and extend into the adjacent lattices, notably the space charge, hence the two-dimensional def...

Effects of density difference of constituent elements on glass formation in TiCu-based bulk metallic glasses被引量：1
《Progress in Natural Science:Materials International》2013年第5期469-474,共6页Zhongyan Zhang Zengbao Jiao Jie Zhou Yuan Wu Hui Wang Xiongjun Liu Zhaoping Lu 
supported in part by National Natural Science Foundation of China (No.51010001 and 51001009);111 Project (B07003);Program for Changjiang Scholars and Innovative Research Team in University;the financial support from "the Fundamental Research Funds for the Central Universities"
Glass formation is generally favored by a large atomic size mismatch among constituent elements,which usually leads to large density differences among them as well.During melting,elemental segregation occurs due to St...
