Chyung et al. [4] reported that glass-ceramics containing finely dispersed mica platelets could be machined by the conventional metal-working tools.
Tanimoto et al. [7] developed a SiC/C composite with high porosity that could be easily machined using WC tools, while the hardness and the strength were quite lower than that of monolithic SiC ceramic.
Janet B, et al. [9] reported that the rare-earth phosphate composites as LaPO4, CePO4, YPO4/Al2O3, LaPO4/Mullite and CePO4/ZrO2 are also could be easily cut and drilled using conventional tungsten carbide metal-working tools, and the materials are all stable to very high temperatures in oxidizing environments (> 1600°C).
Padture et al [10] have developed one kind of plate-shaped SiC/YAG composite with the weak interface bonding that could be machined using WC tools.

Experiments The matrix material was processed by Al, Zn and Cu, the purity were 99.99%.
The bulk Al was superheated to 850 ℃ a period time and then put Cu into the melt.
The dark phase presented is Al-rich α’ phase, the light gray phase surround α’ is the Zn-Al eutectoid, TiB2 particles’ contrast is between α’ phase and the Zn-Al eutectoid which is distributes uniformly in the matrix material with the size of less than 2 μm.
The α’ phase is unstable and then decompose into equilibrium Al-rich α and Zn-rich η phases through two ways.

Al, Ca, Fe and Mg and other non-enriched elements in the atmospheric particle originates from the road dust carried by the motor vehicle at the traffic junctions; the noise pollution emerges from the engine and tire friction.
The non-enriched elements in the atmospheric particulate comes from road dust carried by the motor vehicle at the traffic intersection, such as Al, Ca, Fe and Mg; Cu is discharged by the diesel vehicles; Pb is enriched from the fuel combustion in the soil; S, As and Se comes from the emission of fired coal, contributing to the particulate with large diameter weakly [3].
El-Aassar and Ahmed, who comes from America, predicates the impact of meteorological condition on the traffic noise with the acoustic theory [20].
