not increase the size of large particles. 5 Conclusions 1) B1 structure of TiC has 20 probable states of Ti atom and C atom, D03 structure of Fe3Al has 636 probable states of Fe atom and Al atom. 2) (110... of wave function continuity. Based on it, LIU et al[7] proposed a method to calculate the biphase interface valence electron structure, and found that the electron density of (111)γ //(110)α interface......
[8] studied the pesting of Mo-Si-X (X=Al, Ta, Ti, Zr, and Y) to evaluate the third element effect. They reported that elements that have stronger affinity to oxygen than Si, e.g., Al, Ti, Zr, and Y... et al[11] MoSi2 can dissolve not more than 2.6% (molar fraction) Cr corresponding to the formula (Mo0.92Cr0.08)Si2, since their alloy with composition (Mo0.90Cr0.10)Si2 showed some C40 reflections......
relations of the related metal systems are indispensable for alloy design and processing. The purpose of the present work was to evaluate Au-Ag-Si ternary system and to obtain precise thermodynamic description of this ternary system. Among three binary systems, Ag-Au and Au-Si binary systems have been well assessed thermodynamically by HASSAM et al[7] and MENG et al[8], respectively. Fig.1......

℃ The micro-hardness of the Ni-P and Ni-P-SiC composite coatings is shown in Fig.4. As for as- deposited alloy, the micro-hardness HV50 of Ni-P-SiC composite coatings is 628.45, not too high compared... on chemical composition, structure and crystalline phase. 2) During heating, the amorphous alloy in electroless Ni-P-SiC composite coatings crystallizes, and then reacts with SiC at high temperature......
and thus it is a pure Sn. It should be noticed that there is no any diffraction for Cu-Sn alloys. This suggests that during the film fabrication either Cu-Sn alloy cannot form or it may form but its.... Study of Sn/Ni alloy films electrodeposited as anode materials for Li-ion batteries [J].

to 0.1 V shows a large irreversible capacity. The calculated first discharge capacity based on the formation of Li2O and alloy is 1491 mA?h?g-1, but the observed first discharge capacity reaches 1 923 mA... is related to the trapping of Li. The retention of Li atoms within the lattice of nano-Si was observed by HRTEM[13]. JAMNIK et al[14] believed that some atoms, like dangling bonds and defects sites, have......
