This information is significant from the point of view of functional properties.
During these processes as well as during heat treatment, on the way of obtaining final shape and mechanical properties, intense oxidation of the material surface takes place.
During hot and cold working, including extrusion, an adequate internal structure is formed directly affecting the shape memory effect [9].
In polycrystalline materials, this value is much lower and depends on many factors.
Wasilewski, 55-Nitinol – The Alloy with a Memory: Its Physical Metallurgy, Properties and Applications.

The cement based material is usually used in combination with steel reinforcement, so its alkality will inevitably affect the rate and degree of corrosion for the steel reinforcement, meanwhile, high alkality is a necessary condition for chemical stability of its hydration product.
3 2.9337×10-12 year During the life cycle of the material its manufacture technology has environmental coordination property with some environment recovering function, therefore, this material is a new ecomaterial with excellent environmental coordination.
Summary The alkali activated slag cement based ecomaterial has many advantage, such as: 1. excellent mechanical performances and durability, its 28-day compressive strength reached 104.1-123.8 MPa and the 365-day compressive strength 121.5-144.0 MPa. 2.
The CO2 can be recycled as a resource for the material curing and in comparison with the steam curing, the energy consumption is lowered and the property of the material improved. 10.

However, when the machine running normally many important factors that affect enterprise's efficiency, such as downtime and non-cutting time, are easily overlooked.
The energy ratio change in each band can reflect the different processing condition of mechanical equipment.
The first step to analyze continuous signal is to divide it into different segments, the length of segments is decided by the precision and speed of data process, if the segment is overlong the precision will be high but the real time property will decrease, and vice versa.

Introduction Due to mechanical and physical properties of advanced composite materials, their industrial interest is growing.
The possible delamination could be related more clearly to the mechanical stress (forces) than to local heating.
Optical measuring microscope is used to characterize the delamination factor, which is defined as [6]: (1) where Dmax is the diameter of the zone affected by the superficial removal of material and D0 is the drill diameter (Fig. 5).
Under the cutting conditions used, with low cutting speeds, there are no significant variations; however, the delamination factor decreases by increasing the cutting speed above 70 m/min [9] and the use of sacrificial material continues being positive.
In particular it can be seen how the separation of the layers occurs in a relatively distant area of the edge; this evidence induces to consider the mechanical loads (forces) as the origin of this type of default.

Introduction It is one of the important factors to affect teaching effectiveness and students’ eye health that the lighting of teaching building does not meet the requirements of eye health.
Considering the cost, size, energy consumption, communication range, sending rate and other factors as well as design requirements, Chipcon's CC2430 chip and module is selected.
With the advantages of convenient control and management, good energy saving properties and so on, the system can meet the lighting control requirements of teaching building and has excellent practical value.

The sintering additives and their concentrations significantly affected the consolidation process as well as the properties of composites.
Apart from its extremely high elastic properties, TiB2 exhibits high electrical and thermal conductivity, low specific weight, excellent wear resistance and good stability with various liquid metals.
This set of properties is especially appropriate for the fabrication of highly wear resistant components, such as cutting tools [2, 4, 5].
The wetting properties of liquid Fe or Ni are relatively low at liquid phase sintering which affect low relative density and poor homogeneity.
In order to evaluate mechanical properties of investigated samples Vickers hardness and microhardness were determined (Fig.5).

In general, the properties of the aggregates are strongly related to their composition as well as to the recycling process [12].
Many researchers have been studying the best technologies to obtain green concrete, a sustainable product characterized by improved properties and several advantages such as reduced CO2 emissions or reduction of unused waste products [6-13-14].
This study does not consider the economic and technical factors.
The mixture considered in this research have same workability and mechanical resistance with constant parameters such as w/c ratio, cement content and type of cement employed; making these assumptions can be useful to correctly evaluate the impact.
Furthermore, the mechanical properties of the analysed concrete were not considered and the processes cannot be found in the SimaPro database, so the results come from different criteria used in the evaluation method considered in the software (the method used in SimaPro was Eco-indicator 99).

Introduction Rock mass is a discontinuous geologic body, which is cut by the structural planes of different mechanical properties and space conditions.
And he studied the rock mass deformation, destruction and the basic rules of mechanical property guided by the rock mass structure control theory comprehensively and systematically.
Rock mechanical properties not only depend on the mechanical properties of rock material, and are controlled by the effect of structural mechanics and environmental factors [3,4].
Because rock mass structure is different, so rock mass physical, mechanical properties and the way of engineering rock mass deformation and destruction are also different.
It can be known from Table 1 that the dip angles of AD05-g5, AD13-g5 and AD25-g7 changed little, but trend angles changed 20°and 35 °respectively, which may be affected by the surrounding faults.
