With controlling high pressure nitrogen atmosphere and bottom blowing nitrogen, internal react were investigated by single factor experiment.
Introduction High nitrogen steel was a good mechanical properties and corrosion resistance steel, which is the new material of the most value in the metallurgical field in 21th century.
The main influence factors are nitrogen partial pressure, alloy composition and temperature.
Once these factors are determined, then the nitrogen content in steel through calculation known that saturated solubility of nitrogen.
The pressure is the most significant factor in many factors of affecting nitrogen solubility.

Previously, human factors was left behind and be considered as independent factors with very less contribution to the overall system performance[1].
Researchers conducted their studies on individual variable to measure performance, factors affecting performance and effect of performance; either on individual level or organizational level.
Most of them relate one or two variables or factors affecting performance with the effect or consequences of the level of performance.

The development of the resin modulus is derived using the dynamic mechanical analysis (DMA) tests and the effective mechanical properties of the processing composite are calculated using a micromechanical model.
Lumped material properties are used and assumed to be constant.
On the other hand, the effective mechanical properties of the quasi-isotropic (QI) CFM layer is calculated considering the material properties of the UD layer obtained by the SCFM approach for the same Vf as the QI layer [16].
Local material orientations are employed for the UD and CFM layers separately in order to reflect the mechanical properties correctly.

Summary Underground mining In the slope outer region, as two kinds of mining influence domain in a partially overlapping, the underground mining disturbance influence the slope stability, making the influence domain of the slope rock mass stress field cause the fundamental change; thus affect the slope stability; If you ignore the influence factors of stress history, the analysis result will be inconsistent with the actual situation; Thus affecting the authenticity of theoretical evaluation, so explore the effect of outer region underground mining on slope stability properties, will have important theory and value in use to the similar mining conditions of slope safety assessment and design.
Influence properties of the slope stability caused by the underground mining of slope outside 2.1 Division attributes of deformation superposition From the deformation characteristics to see, in the comprehensive effect domain of open pit combined underground mining, the slope rock mass is influenced by the factors, such as weathering, groundwater, rock mass rheology and the stress release caused by mining, produces displacement vector direction is ui (chart 1).
That is to say the stability coefficient of the slope is a function of sinking, horizontal movement, horizontal deformation, tilt, curvature, the mechanical parameters of rock mass and the slope angle; compared to open pit mining, increased underground mining in the slope to produce a variety of deformation parameters, in different spatial position of underground mining area overlying rock body, the above deformation parameters is absolutely inconsistent; at the same time, these parameters also depends on the combined effect of multiple factors, such as coal mining method, roof management method, the geotectonic distribution, rock strength and so on; this shows that If the effect of underground mining is ignored or not considered, it is obviously faultiness and unreasonable.

The electron-atom ratio (e/a) dependence of the appearance of the lattice modulation and physical properties in β-phase Ti-xNb alloys (x = 28, 30, 34 and 40) were investigated by using some physical properties measurements, compressive test and transmission electron microscope observations (TEM observations), focusing on the β-phase stability.
The microstructure, physical properties, deformation mode depend on the e/a ratio which is closely related to the β-phase stability in Ti-Nb alloys.
In particular, it is very important to reduce the Young’s modulus and to control the mechanical properties in β-phase Ti-Nb alloys for the applications such as artificial joints and dental implants [1].
It is necessary to understand the β-phase stability in order to further develop β-phase Ti alloys because the β-phase stability possibly affects their physical and mechanical properties.
Conclusion It is investigated the effect of the β-phase stability on the physical properties and deformation behavior in Ti-Nb alloy single crystals.

The study of the characteristics of the raw materials; mathematical modeling of the experiment; studied physical, mechanical, thermal, deformation properties of wood-slag composite; studied the influence of the method of its manufacture on the basic properties.
During the experiments, all factors varied at three levels – mainly (0), upper (+1) and lower (-1).
This is due to the fact that all its components in their original form have an amorphous phase in their composition, which positively affects the formation of the thermal insulation properties of the composite material.
Along with the strength and durability of the composite has good thermal insulation properties.
It is proved that the new material has improved physical, mechanical, thermal and operational properties in comparison with competing building materials.
