The damage zone on the tensile surface of the sample is shown as Fig.2(c), which contains a number of discontinuous cracks and crack bridging.
SEM examination on microstructure confirmed that the damage at early stage was controlled by inter-grain slipping and cavitation.

In 3Y-TZP, the grain size must be less than 0.8 and 0.3μm to attain 100%tetragonality in air and in hot (200-300˚C) humid atmosphere respectively.
Nano-sized powders of Zirconia-based ceramics have been synthesised through various wet chemical methods such as sol-gel synthesis[3], polymeric precursor route[4], combustion synthesis[5], hydrothermal treatment[6] and co-precipitation from metal aqueous solutions[7], which are difficult to control the powder size because of during wet chemical processing of the preparation, gels of zirconium hydroxide are interlinked three dimensionally through the oxo- and the hydroxyl bridging and there is entrapment of a large number of water molecules within this gel network.

Table 3 Aggregates physical index Tests Value Requirement[5] crushing index[% ] 7.2 ≤26 Soundness[%] 1 ≤12 Acicular and flaky grain in aggregate[%] 4.6 ≤15 Polished stone value 46 ≥42 Los Angeles abrasion[% ] 9.1 ≤30 The same aggregate gradation as shown in Fig.1 was used in all different modified asphalt pavement evaluation, and specimen fabrication and determination of the optimum asphalt content were based on the standard Marshall Compaction test (JTJ 052-2000).
These specimens are cylindrical, with diameter of 101.6 mm, height of 63.5 mm, compacted with double 50 numbers.

Due to these properties, they are used in a number of applications such as ceramic capacitors[1].The study of BaTiO3-based lead-free piezoelectric ceramic has become a popular reaches field in the world in recent years.
The grain size is about 1 µm.

In the early works, electrokinetic remediation has proved to be a possible way to remove heavy metals from fine grained porous solids such as soil, clay, fly ash and sludge[15, 16].
Fig.2 The variations of pH with time Fig.3 The variations of electric voltage with time Variation of electric voltage with time: As the high conductivity caused by the large number of ions in fly ash causes, electric current was fixed constantly in this study.

The characteristics of that are small number, small scale, insufficient category, narrow choices without thinking of residents’ individual needs at that time.
Daily supporting service facilities are limited, which were built unified by city government or some institutions, including nurseries, canteens, small shops, grains and oil food shops and so on.

Plain weave is the simplest fabric grain which is shown in figure 1 (a) with top, front and side view.

It is estimated that more than half of the cars on the road today ride on alloy rims and the popularity of this wheel style is hard to top for a number of reasons, but there are some potential pitfalls to watch out when an alloy is selected.
While the presence of excess silicon improves age hardening response, it may however reduce the ductility and cause intergranular embrittlement, due to segregation of excess silicon to grain boundaries [1].

Experimental The mix comprised ordinary silicate cement in P.O 42.5 grade, class-F PFA, limestone crushed stone in 4.75~19.5mm grain size, river sand, tap-water and JHY-6000 high-performance water reducer.
The data for the change in length show a number of variations to the change in mass.

Such soft magnetic character is though to be originated because the magnetocrystalline anisotropy vanishes and the very small magnetostriction value when the grain size approaches 10 nm [2,4].
