Introduction Nanocrystalline magnetic materials have outstanding properties thanks to their small grain size.
It is assumed a ferromagnetic material with uniaxial anisotropy.
In other words, the models of Fig. 2 are only valid for phases with very small domain wall thickness, i.e., materials with very high magnetocrystalline anisotropy, as Nd2Fe14B and SmCo5 for example.

Vacuum cover Fig.2 Program one: measure device with a vacuum cover Principle 25 is self-service, which is embodied in two aspects: (1) Make an object serve themselves through the additional function; (2) The use of waste materials, energy and substance.
According to this principle, using magnetic theory, the loading platform is made of permanent magnet materials; the base also installs permanent magnet, whose polar is opposite.

The heightened requirements to the gas sensors characteristics cause the necessarity to develop new materials with the predefined properties.
Also, the numerous studies shows that the mixed metal oxide structures are wide spread as gas sensitive materials, for example, thin films on the basis of metal oxides doped with d-metals [6-8].
The materials prepared by the technique as the result of this procedure were first dried at 150⁰C for 2 h and then annealed at 500⁰C for 5 h in air.

Therefore, to estimate the fatigue life in the application of metals, the key problem is how to calculate the fatigue life of materials and elements simply and reliably.
MATERIAL A�D EXPERIME�TAL METHOD The material used is a rolled bar of 0.42% carbon steel annealed for 1 hour at 840°C.
If used the empirical equation of 16.0 73.1 pb n εσσ = [4], where bσ is the tensile strength of materials, to Eq.(2), the constants in all equations can be estimated.

Introduction It is well known that aluminum industry continues to face a variety of challenges from competing materials, changes demands from customers for increased quality and reduced cost of aluminum products.
Experimental technique The raw materials used for AlSrTiB master alloy processing were: AlTi10 (as bar with ∅30 and length 200 mm), AlSr10 (as wire with ∅9.7 mm) and AlB8 (as micro-blocks).
Results and discussions The AlSrTiB master alloy was produce in order to obtain a new material which can realized in only one material both grain refining and modification of eutectic silicon in aluminum alloys.
