The additions of Mn and Cu into Ti-rich TiAl alloy increase the free electron densities in the bulk and the grain boundary simultaneously[9].
The Nb ratio curve is higher than the Ti ratio curve, this may be due to the increase in the number of d electrons of the Ti and Nb elements, as it is known that Ti and Nb atoms have 2 and 4 electrons in the 3d and 4d orbital, respectively.

By pressure die-casting, it is easy to generate grain coarsening of casting structure and uneven distribution, [5] so that it is difficult to ensure the requirements of mechanical properties.
The basic parameters of the simulation settings are as follows: Temperature: 300 degrees, Speed: 1mm/s, Friction factor: 0.3, Grid number: 10,000, Steps: 0.2 mm (the minimum grid is 0.6 mm steps is a minimum of 1/3), Total steps: 115 (when the convex mould pushes down about 23mm, simulating stops).

MIC-840-01 can not only automatically determine the air-void parameters of hardened concrete (such as the number of bubbles, the spacing factors, mean air void diameters and so on), but also manually separate the non-air-entraining bubbles from other bubbles for making quantitative description of the air-voids structure of concrete.

In the case of fine-grain stoneware produced from powder of comparatively narrow particle size
distribution, the craters are smaller and more uniform.
In fact the scanning width can be increased twice so that only half the number of scanners is required.

However, with the narrow ceramic devices, functional ceramic films and the emergence of a number of nano-structures, thermal barrier coatings, anisotropy is particularly important and significant, while the directional growth of technology development makes no longer applications [1-3].
In most cases, the isotropic crystal is preferred, because there is no need to grow or align the grains in a specific direction in order to utilize the maximum mechanical moduli.

It can be seen that the total number of pores with increasing dynamic load increases, and fitted equations under three confining pressure states are all linear equations , their pertinence are well.
With the increasing of axial dynamic stress, the slide-zone loess begins residue deformation and soil mass structure begins destruction, parts of simple grain or cumularspharolith are broken and adjacent porosity are filled with these soil particle.

Precipitation in the hot solution, on one hand, could increase the solubility of precipitation and lower the solution relative saturation so that a large crystal grain might be obtained; On the other hand, improving the temperature of solution would accelerate the ion diffusion speed, thereby promoting the crystal growth and the formation of crystal precipitation.

If rock contains many hydrophilic and dissoluble mineral, the connection among rock grain is weakened which lead to the decreased strength and rock’s softening.
Considering the occurrence condition in Huaibei mining area, there are a large number of structural planes distributed in rock mass, and the dirt band, influenced by advance abutment pressure and repeatedly bracing by supports, has rich fracture development, so the value could be 0.1.

There is obvious grain refinement effect; The amount of N doping and B is low, two obvious resistance decreased steps of the film resistance temperature characteristic curve appear, which can provide key materials for multilevel storage C-RAM; When the doping amount is higher, amorphous resistance in a large temperature range is very narrow, which greatly enhance stability, and at the same time, amorphous resistance also have improvement of different degrees; Doped with Ag and Sn atoms, while the amorphous and crystalline resistance decreases, it can reduce the crystallization activation energy, which can accelerate the crystallization rate.
