Property of Steel Fiber Steel fiber is a kind of long fiber into which raw materials such as thin steel scrap and old steel wire rope after disconnecting and cleaning are cut.
As a good choice for reinforced material in bituminous mixture , steel fiber’s primary strength include tensile strength and adhesion strength.

Introduction Powder Extrusion is a manufacturing process, which allows the production of fully dense materials.
Presintering or preheating the compacts before extrusion decrease the hardness of the material.
At the periphery, the material experiences a higher strain.
On the other hand, the extrusion process leads to an increase of hardness in the material (Table 2 vs.

Introduction Ultra-fine grain organization has excellent mechanical properties, such as high strength, good low temperature impact toughness and dynamic strength in high speed rate condition , therefore it will be widely applied to the engineering materials in the future [1,2].
There are many factors in relation to the refinement of steel material organization, among which temperature and strain are the necessary conditions of fabricating ultra-fine grain.
The multi-direction and not simultaneously process were more effectively import large plastic strain into centre of materials.

Introduction Zinc Oxide (ZnO) is a wide-bandgap II-VI material with a promising future in blue-to-ultraviolet (UV) optoelectronic applications.
The discrepancy may be due to the different approach of probing the materials as well as the different working principle of these techniques.
Both results are contradicted with each other due to different approach of probing the materials as well as the different working principle of these techniques.

It is beautiful in shape so can naturally integrated into the scenery and this kind of bridge bears more by fully using compressive properties of the material[1].
So in ancient times when materials were relatively undeveloped a larger span of the bridge could be adopted with a shape of an arch and the arch bridge would be strong and serve a long time.
