In artificial tooth application, pure zirconia with high strength is needed, thus controlling crystal and grain sizes is a crucial factor which affect the properties.
This material can be used for many applications due to its bioinertness, chemical resistance, high strength, low thermal conductivity, high mechanical properties [1-5].
The use of a nickel crucible and careful temperature control are critical factors in optimizing the alkali fusion process for zirconium compound production.
High-purity fine-grained zirconia offers remarkable mechanical properties that make it suitable for dental applications, especially for crowns and bridges.
This high purity and small crystal zirconia will give superior mechanical properties which are suitable for artificial dental applications.

The important role of dissolved elements ( Mn,Fe) in the process of rolled products and their effects on final properties Dr.
Jochen Hasenclever Hydro Aluminium Deutschland GmbH , Research and Development , Post-Box 2468 , D - 53014 Bonn - Germany Keywords: AlMn-,AlFe-alloys , recovery, recrystallisation, grain structure, mechanical properties Abstract The important role of dissolved elements, such as manganese or iron, in the production process of rolled material was in the focus of this investigation.
Introduction Important aspects of rolled products are their softening and recrystallisation behaviour and the resulting properties. [1-3].
The content of manganese / or iron was calculated from the resistivity using the factors 3.83 for Mn and 3.2 µohm/wt.% for iron.
The decomposition of Mn during preheating is strongly affected by the element Fe than by Si.

Introduction When developing protective coatings firstly it is necessary to take into account that most the polymeric materials produced on an industrial scale are not sufficiently resistant to atmospheric factors and mechanical impact.
Naturally, the change of physical and physico-mechanical properties occur in the composition.
In this respect, the research results have both fundamental and applied tendency and can be used for the development of new materials and coatings to protect buildings, facilities and objects of historical heritage from adverse factors.

Specimens composed of columnar grains or single crystal exhibit excellent tensile properties.
But titanium will react with all commercial ceramic mould materials, which in turn affect the microstructure and mechanical properties.
Withdrawal velocity is an important factor affecting the macrostructure.

Withdrawal velocity is the significant factor affecting the macrostructure and solidification front changes when it changes from concave to flat and then to convex with the decreasing of withdrawal velocities. 4.

The electrical properties of aircraft are also affected by the temperature changing.
Internal relevant scientific and research institutes have been studied the electric properties of materials with different temperature to meet the design requirements [3], but there is few research on the variation of dielectric properties with the temperature changing.
Results and Discussion The influence of temperature on the properties of materials.
The influence of permittivity on the wave-transmitting properties for radome.
But the radome can not meet the requirement of using due to that the mechanical properties were decreased seriously.

Introduction Wear and corrosion is an important failure form among mechanical parts.
During the usage process, working equipment or transmission system of machinery equipment could become invalid unavoidably due to the quality of material processing and assembly, climate and work environment, quality of fuel and lubricating materials, operation and other factors[1-4].
These changes will damage the formal superficial size and property of the surface of mechanical parts, which deterioriate technology gradually and lead to mechanical accident in the worst.
Smaller heat affected zone.
High hardness, high wear resistance, high bonding strength, suitable for steel, iron, copper, aluminum and other metal materials, can solve the high wear, corrosion, scratches, cracks, surface failure of precision repair, edges and corners, interior angles defect repair, and repair the surface of special shaped puzzle that can strengthen the surface properties of components to extend the service life of components in the broad field of surface engineering applications.

PFZ are believed to affect the mechanical properties of the alloys in different ways [1].
It has also been observed that PFZ have no influence on the mechanical properties [4].
One of the reasons is that many microstructural factors near grain boundaries contribute to the mechanical properties, e.g. the width of PFZ, size of grain boundary precipitates and so on.
To predict strength and ductility of an alloy, therefore, it is essential to estimate the correlation between such mechanical properties and the corresponding microstructural factors.
Such a capability would be important for optimization of mechanical properties and design of new alloys.
