As a result, the selection of a solid solution of a large number of dispersed carbides on the basis of the alloying components,ie is aging.
The microstructure of the hardened surface of the specimen is a fine-grained martensitic structure with dispersed insoluble inclusions of carbides and nitrides (Figure 2).

Compression perpendicular to grain as well as shear strength of wood are usually too weak to resist earthquake forces, which may lead to cracks on tou-kung; wood material is easy to distort due to air shrinkage, which is a main inducement for distortion and slack of members of tou-kung; environment of dampness and airtightness may cause decay problem of tou-kung members; anisotropic characteristic of wood material makes its mechanical as well as physical performances discordant, which may lead to cracks of tou-kung under loads
In fact, the more the layer number of tou-kung is, the lower value of k be [12].

When mole fraction of 4HB is less than 15%, the number of branch chains is relatively less, along with the increase of 4HB’s mole fraction, the distance between molecules increases, which leads to the decrease of intermolecular forces.
So edges and corners tend to grow thinning in front of the other crystalline grains, which increases dendritic growth trend and finally forms dendritic crystal.

Technology and Experimental Research Plan “Liquid wood” grains can be processed by mold injection, extrusion, calendering, blow molding, deep drawing or pressing into molded parts, half-finished product, sheets, film solder profiles, [2, 4].
After the orthogonality and the number of degrees of freedom conditions have been checked, there were 16 experimental tests to be conducted.

Large number of studies carried out home and abroad on the effective utilization of sludge dredged.
Grain size test uses laser particle size analyzer.

Fig. 2 shows the AFM photo of the fabricated VOx thin film, in which it can be found that the diameter of crystal grain is in the range of nanometer.
Through a large number of experiments, a list of optimized process parameters to fabricate VOx thin film with nanostructure in our laboratory are gained and summarized in table 1.

Among the materials termed as martensites include a large number of alloys with the common feature of undergoing martensitic transition (MT).
Phenomenological Modeling The model is based on a strain formalism within a coarse-grained Ginzburg-Landau framework.

The effect of silicon contained in iron alloy substrates subjected to the process of zinc-coating in the conditions of metallization (440-460°C) has been explained a number of times [1-7].
Low solubility of silicon in phase z leads to its segregation at the border of grains and formation of areas of liquid Zn between z crystals [6].

It will create the most suitable environment for plants thereby to increase the grain yield and revenues.

Introduction Zn-Al-Cu type alloys are characterized by a number of advantageous properties which include: good castability, good tribological properties, low energy for shaping the product.
The main alloying element is aluminum [3], its addition increases the castability, influences the size reduction of grains and improves the mechanical properties [5].
