Three dimensional dendritic morphology and orientation transition induced by high static magnetic field in directionally solidified Al-10wt.%Zn alloySansan Shuai1,Xin Lin2,Yuanhao Dong1,Long... of α-Al was found to transform from the traditionally expected <100> to<110>. The dendrite orientation transition(DOT) in Al-10 wt.%Zn alloy can be attributed to the effect of applied......
Chemical Bond Calculations of Crystal Growth of KDP and ADP Xue Dongfeng1,Xu Dongli1 (1.State Key Laboratory of Fine Chemicals, Department of Materials Science and Chemical Engineering, School of Chemical Engineering, Dalian University of Technology, Dalian 116012, China) Abstract:A novel method was proposed to calculate the crystal morphology (or growth habit) on the basis of chemical bond......
-crystalline materials, the influence of external constraint and rolling geometry on the deformation behaviour of copper single crystals with {123}<634> orientation was investigated by embedding them into metal frames of different strengths. The metal frames were made of aluminum and mild steel, respectively. The results show that the deformation banding degree of the crystal increases......

SUGIMOTO et al [4,8] also studied the effect of crystal orientation on the strain-dependent damping of magnesium alloys using different testing method. According......
by crystal plasticity simulation[J]. Intermetallics, 2011, 19: 820-827. [7] FALLAHI A, ATAEE A. Effects of crystal orientation on stress distribution near the triple junction in a tricrystal γ-TiAl[J... crystal at room temperature was simulated. The tensile orientation was ordinary slip orientation [10], super slip orientation [01], twin slip orientation [11] and arbitrary orientation [01], respectively......

The single crystal superalloy specimens with [001] orientation were cast by crystal selection method in the directionally...), respectively. The crystal orientations of the specimens were determined by Laue X-ray back reflection method, and the crystal orientation deviations of the specimens were maintained within 10......
