Journal ArticleDOI
Extraordinary high ductility/strength of the interface designed bulk W-ZrC alloy plate at relatively low temperature.
Z.M. Xie,R. Liu,R. Liu,Shiding Miao,Shiding Miao,Xinglian Yang,Xinglian Yang,T. Zhang,T. Zhang,X.P. Wang,X.P. Wang,Qi-Wu Fang,Qi-Wu Fang,C.S. Liu,C.S. Liu,G.-N. Luo,Y. Y. Lian,Xialin Liu +17 more
TL;DR: This processing route offers the special coherent interfaces of grain/phase boundaries and the diminishing O impurity at GBs, which significantly strengthens GB/PBs and thereby enhances the ductility/strength/plasticity of W alloy and can be used in the future to prepare new alloys with higher ductile/strength.
Journal ArticleDOI
Nanostructured yttria dispersion-strengthened tungsten synthesized by sol–gel method
R. Liu,Z.M. Xie,Z.M. Xie,Qianfeng Fang,Qianfeng Fang,T. Zhang,Xianping Wang,T. Hao,Chao Liu,Y. Dai +9 more
TL;DR: Yttria dispersion-strengthened tungsten with both enhanced strength and ductility was synthesized through sol-gel method followed by sintering and high-temperature swaging.
Journal ArticleDOI
Microwave synthesis and properties of fine-grained oxides dispersion strengthened tungsten
TL;DR: In this paper, it was found that the addition of Y2O3 nano-particles could significantly hinder the grain growth of tungsten in the consolidation process, decreasing the average grain size from 3.2μm in pure W down to 0.7μm.
Journal ArticleDOI
Spark plasma sintering and mechanical properties of zirconium micro-alloyed tungsten
TL;DR: In this paper, Zr was used to capture impurity oxygen in tungsten and form nanometer scaled ZrO2 particles, which significantly increased the fracture strength and toughness of tengsten.
Journal ArticleDOI
Mechanical properties and thermal stability of pure W and W-0.5 wt%ZrC alloy manufactured with the same technology
H.W. Deng,H.W. Deng,Z.M. Xie,Yang Wang,Yang Wang,R. Liu,T. Zhang,T. Hao,Xianping Wang,Qianfeng Fang,Congwei Liu +10 more
TL;DR: In this paper, the mechanical properties, microstructure and thermal stability of hot rolled pure W and W-0.5%ZrC alloy manufactured using the same technology are systematically studied.
