From the as sintered materials, specimens of approximately 6 x 3 x 3 mm3 were cut and grounded for tests.
In that way, the amounts of additive formed glassy intergranular phase that were decisive for the creep results of these materials.
Like this, these materials are less subject to the softening of the intergranular phase and consequently, present larger creep resistance that other Si3N4-based ceramics.

If these waste materials can be used, not only greatly reduce waste emissions, but also can reduce the rocks, sand mining, to improve the ecological environment can be described as dual.

Compared with those semiconductor based transparent conductive materials, metallic based materials have higher transmittance in the visible light and lower electrical resistance.
The metal films, which are quite different from bulk materials, consist of metal particles and voids, hence, the optical constant changes with the film thickness.

In the broad sense, ancient buildings form is recreated consisted with the traditional cultural characteristics, and the narrow sense is that ancient buildings form was restored by using of traditional building materials in a particular range[4].
They have distinctive regional features due to topography of cutoff basin, climate of small wind and rainy, main materials used in wood, low-impact of orthodox north architecture and so on.
Thirdly, it has both a set of traditional construction craft and scientific use of local materials such as bamboo, wood, soil and stone.
The design and construction depend on these local materials lead to low cost.

Mechanical alloying, developed by Benjamin in 1970’s to produce oxide-dispersion-strengthened alloys for high temperature structural applications [7], has been widely used to synthesize various metastable materials including supersaturated solid solutions and submicron, nanocrystalline or amorphous alloys [8,9], due to its simplicity, the relatively inexpensive equipment, and the possibility to synthesize essentially all classes of materials.
Experimental Commercial elemental Ni and Fe powders, with a medium particle size of about -400 mesh, were used as the starting material.
