Nucleation and three-dimensional morphology of intragranular ferrite in a vanadium microalloyed steelKaiming Wu and Xinlai He Materials Science and Engineering School, University of Science..., which, in turn, promotes the formation of intragranular ferrite. The morphology of intragranular ferrite changed with undercooling. At higher temperatures intragranular ferrite is nearly equiaxed whereas......
morphology. This study proposes four-stage evolution process based on the shear stress-strain curve. During the shear process, coral sand particles slide and rotate within the interaction band, causing... the roughness of slabs is, the larger the shear stress is, the more obvious the contraction effect is and the more the particles break. Furthermore, the change in particle’s 3D morphology during......
The 3-dimensional morphology of dendrite during equiaxed solidification of an Al-5 wt.% Cu alloyXiaoping Ma,Dianzhong LiShenyang National Laboratory for Materials Science, Institute of Metal Research, Chinese Academy of Sciences摘 要:In a sample quenched during equiaxed solidification of an Al-5 wt.% Cu alloy, the multi-scales 3-dimensional morphology......
morphology is cellular or globular. The eutectic transformation L→α-Mg+β-Mg17Al12 and microsegregation in conventionally solidified AZ61A alloy are suppressed to a great extent. The β-Mg17Al12 phases located... solidification microstructure dominantly consists of supersaturated α-Mg solid solution. The mechanical properties and fractographic analysis reveal that the fracture mechanism and corresponding morphology......
">The fabrication peculiarities of low-agglomerated yttria(Y2O3) nanopowders via thermal decomposition of sulfate-doped precursor with transient morphology were studied.It was determined that Y2(OH)5(NO3)x... the surface diffusion during heat treatment thus retaining quasy-spherical morphology and low aggregation degree of Y2O3 nanopowders.Sulfate-doped yttria nanopowders with medium particle size of 53±13 nm......
