When the same quality BaO was used to replace CaO, the mole number which O2- was brought into slag was decreased.
An analysis from the point of silicate precipitation, in the high temperature region, crystal nucleus was easy to form in liquid slag film, which was unfavorable to the grain growth.

A number of authors reported the synthesis of ferrimagnetic glass-ceramics in many systems, for example, SiO2-CaO-Fe2O3[6], SiO2-CaO-Fe2O3-B2O3-P2O5[7,8], SiO2-Na2O-CaO-P2O5-FeO-Fe2O3[9], CaO-P2O5-SiO2-MgO-MnO2-Fe2O3[10], SiO2-CaO-Fe2O3-ZnO[11], Li2O–MnO2–CaO–P2O5–SiO2[12].
For the crystal, the saturation magnetization increases with increasing crystal grain size, but the coercive force decreases[16].

Single crystals of Ni3Nb and Ni3Ti and crystals with directionally oriented large grains of Ni3Sn were grown by the floating zone method under a high-purity Ar gas flow.
Since there is a large number of hcp based GCP type compounds with c/a>1.60, new compounds showing anomalous strengthening behavior are expected to be developed.

At 1600 ºC, the areas with a high titanium contents (Ti particles accumulation) results in a residual presence of α precipitates mainly in the β grain boundaries.

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.

Dissimilar welding often leads to low mechanical properties owing to the metallurgical changes such as micro-segregation, precipitation of secondary phases, presence of porosities, solidification cracking, grain growth in the heat affected zone (HAZ) and loss of materials by vaporization.
With further increase in number of cycles, the scale becomes darker.

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].

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].
