The influences of various heat treatment systems on the structure and properties of the glass-ceramics were investigated simultaneously.
Compared with natural stone materials, sintering glass-ceramics decorative materials possess the following advantages: dense structure, high strength, and erosion-resistance.
Heat treatment schedule for the glass ceramics 3.2 Structure analysis The results of XRD spectra of glass and glass-ceramics are shown in Fig. 3.
According to the theory of glass chemistry, crystal is very effective to increase the bending strength of glass-ceramics.

Finally, the structure characterization of the chitosan was studied using Fourier Transform Infrared Spectroscopy (FTIR).
When ammonia introduced on the surface of the chitosan, the ammonia molecules interact with the chemisorbed oxygen and release the electrons within the chitosan structure as explained in Eq. 3.
The appearance of N-H group within the film provides evidence that the domain functional group for sensing mechanism in chitosan film exists within the structure even after it was processed into film.

The effect of heat treatment temperature on structure of AAO film was researched.
Because of the regularity of cell-pore structure these films are widely used as templates for the growth of low-dimensional nano-materials and as a three-dimensional micro/nanostructure itself, and have recently been proposed in optical, electrical, micro-mechanical fields, medical and biological [1-4].
The effect of heat treatment temperature on structure of AAO film was researched.

Composite fluoropolymer coatings were obtained on the base layers in two ways allowing the formation of two different types of morphological structure: a continuous polymer film and a multimodal islet relief.
However, the conducted studies of the structure of oxide coatings formed by this method show that in some cases the level of their barrier properties does not fully meet the requirements for the protection of structures and apparatuses [5].

Plotting S versus W is quite useful as it gives insight about changes in defect structures [59].
Points deviate from the straight line represent defects with different structure.
Three methods have been developed to enable PAS measurements in all structures and geometries.
New Physics Revealed by PAS The high sensitivity of PAS and capability to probe atomic scale defects and measure the change in their structure, size, and characteristics including chemistry and charge state make it a unique tool in materials science revealing new physics in electronic and photonic materials and providing the mechanisms behind interesting phenomena in damage accumulation and recovery.

It can be got available treatment uniform structure with proper γ'phase size, with high-temperature tensile strength up to 750MPa, elongation of 17% reduction of area 22%.
Solution treatment lead cast structure γ'phase partially or fully dissolve back into the matrix, and uniformly dispersed precipitated in the subsequent cooling process, and the aging process will promote the full benefit of M23C6 carbide precipitation.
It has been completely comparable to meet our customers' chemistry requirements for DZ417G alloy.
Compared with synthesis of DZ417G superalloy in the laboratory,mass production was faced too many problems, such as composition segregation, inhomogeneity of structure and so on.

In order to discovery the effect of metal element on structure and catalyst efficiency, the obtained three MMCs were made from deferent three metal salts groups, which including ZnCl2 to NiCl2 to K3Fe(CN)6 molar ratio of 4:3:1 (MMC-1), ZnCl2 to NiCl2 to K3Co(CN)6 molar ratio of 4:4:1 (MMC-2), and ZnCl2 to NiCl2 to K4Fe(CN)6, respectively.
Significantly, the MMC-3 only exhibited a broad peak at 2θ = 23.6° (d = 3.8 Å) between 2θ values of 13.5° and 25.6°, which means that the crystallinity of the MMC-3 is substantially low and tends to be an amorphous structure.
Since the mechanosynthesis of this study are efficient and effective, further work is underway to obtain mechanistic insight of complexes reconstruction under grinding conditions and to improve the activity via optimization of the multi-metal cyanide complexes and co-catalyst structure.

XPS depth profiles show that the film possesses a smooth graded interfacial structure that boost mechanical stability.
The XPS depth profiles indicate that the titania film has a graded structure at the interface with the NiTi substrate.
Moreover, there is a smooth graded interfacial structure that can provide sufficient mechanical stability.
