L. Zeng,L. Zeng,Rui Gao,Qianfeng Fang,Qianfeng Fang,Xianping Wang,Z.M. Xie,Z.M. Xie,Shu Miao,Shu Miao,T. Hao,T. Zhang +11 more
TL;DR: In this article, a bulk Cu/Ta nanolamellar multilayers with an individual layer thickness from several micrometers down to 50nm were successfully fabricated via a combination of cross accumulative roll bonding (CARB) and an intermediate annealing step.
Journal ArticleDOI
Recrystallization and thermal shock fatigue resistance of nanoscale ZrC dispersion strengthened W alloys as plasma-facing components in fusion devices
Z.M. Xie,Shiding Miao,Shiding Miao,R. Liu,L. Zeng,L. Zeng,T. Zhang,Qi-Wu Fang,Qi-Wu Fang,C.S. Liu,X.P. Wang,Y.Y. Lian,X. Liu,L.H. Cai +13 more
TL;DR: In this paper, the effects of edge-localized mode like transient heat events on the as-rolled and recrystallized WZrC were investigated carefully by employing heat treatments with isochronal experiments, the evolution of tungsten grain size/orientation, second phase particle distribution, thermal conductivity and mechanical properties were systematically studied.
Journal ArticleDOI
Development of interface-dominant bulk Cu/V nanolamellar composites by cross accumulative roll bonding.
L. Zeng,Rui Gao,Xie Zhenwen,Xie Zhenwen,Shiding Miao,Shiding Miao,Q.F. Fang,Q.F. Fang,X.P. Wang,T. Zhang,Congwei Liu +10 more
TL;DR: An attractive bulk Cu/V nanolamellar composite is reported that was successfully developed by integrating interface engineering and severe plastic deformation techniques and illustrates that Rayleigh instability is the dominant mechanism driving the onset of thermal instability after exposure to 800 °C.
Journal ArticleDOI
Characterization of oxide dispersion strengthened ferritic steel fabricated by electron beam selective melting
TL;DR: In this paper, solid blocks and walls of the oxide dispersion strengthened (ODS) ferritic steel with nominal composition of Fe 18Cr 2W 0.5Ti 0.3Y2O3 were fabricated by electron beam selective melting (EBSM) method.
