The common conclusion drawn from LDOS and the t otal structure energy difference of amorphous alloy Ni 64 X 16 Al 20 to crystal alloy is: when transition element Ir, Pt, Rh, Pd, Au, Ag, Cu is added into NiAl alloy, the amorphous alloy forming ability we akens in the same order.
The linear and piecewise linear interplotion function for displacement interplotion are used for the transition element formulation according to the displacement compatibility requirement between element interfaces.
Secondly, the effort is made to develope new type of transition element for multi-scale fatigue damage simulaton of long-span structures for the transition between elements for the hot spot stress analysis and the structural element.
In this paper, the continuous conditions for the displacement between the beam element and the plane stress element are accomplished by introducing a kind of transition element. Furthermore, the combuied finite element model of the members and body is established. The analysis on frame structure is completed.

Redox and spectroscopic properties of the eightcoordination complexes of the transition element Mo and lanthanide element Eu and Er with N,Ndiethyldithiocarbamate (dtc) were characterized by cyclic voltammetry and UV Vis absorptive spectra.
Transition element (Mn, Cr, Cu) substituted titanate nanotubes were fa bricated by a simple method, i.e., hydrothermal method. The precursors used were Mn, Cr and Cu doped anatase TiO2 n anopowders, which were 20～30 nm in diameter. The obtained samples were characte rized by SEM, TEM, XRD, EDX, PL and Raman spectra.
Negative electrodes for use in nickel hydride batteries were prepared from Mm(NiCoAlMn) 5 alloy being doped of transition element V It was found that,the negative electrodes have higher specific capacity and longer cycle life by measuring its properieties
It appears from the above study that Al plays a significant role in the stabilization of the bcc phase in the transition element alloys.
In this article, enhanced diffusion through an activated layer at the grain boundaries has been modeled for the case of tungsten sintered with transition element additions.
Effect of Transition Element Ions on the Catalytic Activity of Titanium Dioxide during Chemical Deposition of Metallic Copper
The effective charges are found to decrease regularly in the sequence F->amp;gt;H2O>amp;gt;NH3>amp;gt;Cl->amp;gt;Br-, while the changes with the transition element are found to agree with the known properties of the compounds.
