The shift of the representative peak of magnetite towards the higher wave numbers shows a gradual substitution of Fe(III) ions by Cr(III) ones.
The oxide layers formed during 48h oxidation up to 823K and 24h oxidation up to 873K are relatively thin since steel grain boundaries are visible through them.

These ferrites can be synthesized by a number of methods such as combustion[2], ceramic[3], co-precipitation[4], precursor[5], hydrothermal method[6], sol-gel[7], refluxing[8], high-energy milling[9], etc.
A typical grain is about 33 nm after microwave heating at 860℃ for 30min while the powder has a single-phase (Ni0.5Zn0.5)Fe2O4 structure. 2.

The large number of experimental works with different results about hydrogen accumulation in zirconium alloys make complicated to predict mechanical properties altering of zirconium parts exploited in hydrogen contain media.
Saturation occurs linearly up to the nucleation and grains growing of the new phase, when it is likely thermodynamically under these experimental conditions.

It can be seen that
the section could be divided into three layers: the
outermost is oxidation and adhesion layer, the middle is
deformation layer in which crystal grains are drawn along
the motion direction and form fiber structure, and the
inner is the matrix.

Therefore, the peak appeared at this location is deduced source from the Gd2O3 which not entirely solute into the cubic lattice and stay in the grain boundary.
More Gd3+ introducing lead to the local structure of Y3+ changed and the coordination of number is intended to 8.

But the result is diversity, the accuracy is highly dependent on the number of test and related empirical formulas[6-9].
Fig.2 The requirements of size for different shape specimens (3)To describe the rock lithology, we focus on structural characteristics of its structure, such as grain thickness, arrangement and joints, bedding and other developmental characteristic and degree of weathering, etc

The optimum permeability of a groyne is dependent on various boundary parameters (flow velocities, local turbulence, grain size distribution, etc.) and is strongly interrelated with structural conditions of the groyne field (number and length of groynes, spacing in flow direction).

Diamond crystals exhibit anisotropic characteristics in their elastic behaviors, so the Young’s modulus of the polycrystalline diamond film should be related to grain orientations to a certain extent[6,7].
Generating from combined actions of the Young’s modulus of a large number of orientations, The Young’s modulus in polycrystalline diamond film goes between the minimum and maximum Young’s modulus of single crystal.

Though heat-resistant and stainless steels differ from each other, they have a number of common physical and mechanical properties that determine their common technological properties with respect to machinability by cutting.
problems in cutting stainless and heat-resistant steels are determined by the following factors: - high hardening of the material during the cutting force deflection considering specifics of the lattice structure; - low thermal conductivity of the material machined, which causes an elevated temperature in the contact zone and activation of adhesion and diffusion phenomena; - the ability to maintain the initial strength and hardness at elevated temperatures, which leads to high specific loads on the contact surfaces of a part with a cutting tool; - great abrasive capacity of high-temperature and stainless steels induced by the presence of a second phase (except for a solid solution) forming inclusions of intermetallic compounds; - reduced vibration resistance of the cutting motion caused by increased hardening of stainless and heat-resistant materials at uneven flow of their plastic deformation; - low surface quality due to increased plasticity of hard-to-work materials; - considerable grain
