Introduction Titanium alloy is widely used in the fields of aviation, aerospace and automobile industries for its excellent properties (corrosion resistance, high specific strength and heat intensity).
That is to say, dynamic cutting force in the traditional milling process will lead to the dynamic displacement of the workpiece, affecting the deformation and the geometric accuracy of the workpiece.
Selections of factors and levels are listed in Table 4.
Thus, the values with the highest S/N ratio of factors in the experiments will give the best performance.
(3) The optimum control factors for the thickness error and the deflection displacement of thin-walled parts of the titanium alloy were obtained.

Introduction Titanium and its alloys are used in aerospace, chemical and biomaterials applications because of their excellent combination of properties such as corrosion resistance, biocompatibility and mechanical properties, etc. [1-3].
Two main factors have been suggested as responsible for the poor tribological properties of titanium alloys [5]: 1.
The ANOVA was used to know the effect of factors on the sliding wear behaviour.
The percentage contribution of β solution treatment temperature is very less as compared to other factors is about 7%.

A previous study indicated that bonded joints can sustain higher loads and are lighter than mechanical interfaces [2].
Finite element model A three dimensional finite element model was created in PATRAN, using solid brick and wedge elements with orthotropic material properties for the composite open-end cylindrical laminated shell and the repair patch, with a stacking sequence of [45/-45/0/90]s, and isotropic properties for the adhesive, as in Fig.2 shown.
Fig. 7 The stresses of the bottom surface on the fourth layer Fig. 8 The stresses on the central of composite open-end cylindrical laminated shell As shown in figure 7 and figure 8, type-A, type-B and type-E are the main factors for the changed stresses of the fourth layer and the central of whole model.
Fig. 11 The stresses of the bottom surface on the eighth layer As shown in figure 11, type-C, type-D and type-F are the main factors for the changed stress of the eighth layer.
For the disbonded types, the type-C for the stress is the greatest factor than other disbonded types.

The effect of aluminium sulfate on cement properties was studied systematically and the mechanism was analyzed using XRD and SEM tests.
Multiple measurements are employed in this paper to study systematically the formation and development regulation of cement under the action of aluminium sulfate, such as setting time, fluidity, drying shrinkage and mechanical properties.
As can be seen from the above study, different content of aluminium sulfate has different effect on the properties of cement.
That is, the concentration of calcium in liquid and the PH are main factors.

The distribution of temperature and porosity could be used for more precise calculation of internal stresses in cast component under loading conditions with respect to the structural factors.
There are many applications of cast super-invar components in axisymmetric assemblies because as-cast microstructure of the alloy ensures macroscopic isotropy of mechanical properties [7] over the volume.
Such information could be used afterwards for more precise prediction of internal stresses in cast component under loading conditions with respect to the structural factors.
Modelling of Grain Structure The growth morphology and scale of microstructure in a casting process are directly related with the macroscopic mechanical properties of the final product.
The calculated grain parameter together with dendrite arm spacing influence on mechanical properties of cast alloys owing to variation in growth conditions during radial solidification of cylindrical casting.

Because of the water absorption rate of aggregate after wrapped film depends on the water absorption rate and complete degree of thin film, therefore, water absorption rate and strength of membrane structure have directly affected on the water absorption rate and crush indicators of recycled coarse aggregate 2.2 The influences of asphalt pretreatment technology on physical and mechanical performance of recycled coarse aggregate.
In consideration of choice for water absorption rate from acetic acid resin, asphalt factors the pretreatment of the test to select the lowest water absorption rate(That is acetic acid resin mixes with 6% spirit of vinegar and infiltrates eight hours; Asphalt content 2% xina water , infiltrates 2 hours), and compare the unmodified urea-formaldehyde resin before with the pretreatment of recycled coarse aggregate basic performance comparison, The results as shown in figure 3 below (recycled coarse aggregate performance of the various data calibration marked as 1, the infiltration of preprocessing performance indexes of the aggregate respectively with corresponding, taking ratio for the vertical axis).
That is to say, through infiltrating processes, enhancing the basic mechanical properties of recycled coarse aggregate is feasible.
(3) The effect of using asphalt to pretreated the recycled coarse aggregate is better than acetic acid resin, and also has a more obvious effect on improving the mechanical properties of recycled coarse aggregate; the test of the best improvement effect with using asphalt to infiltrate and pretreat the recycled coarse aggregate is that: adding 2% xina water into the asphalt and then infiltrating 2 hours

White carbon black's rubber reinforcing effect depends on its particle size, surface properties, structure, and its dispersion in rubber.
Though using resin acceptor to modify the White carbon black can change the surface physical and chemical properties, and improve the compatibility between rubber molecules and the interaction, processing technology to improve performance, increase the reinforcement of silica.
The main technological conditions affecting the reaction conditions include: hydrochloric acid dosage, reaction concentration, reaction temperature, Wollastonite particle size, reaction time and so on.
(2) The acid-insoluble impurities that Wollastonite contained in the test are a most important factor that affects the quality of silica.
(3) Silica purification method and the location of the processes is one of the most important factors of production which need to be further refined through pilot studies.

The trend of modern civil engineering involves buildings and structures with precisely defined properties and parameters.
The basic properties of fibres are indicated in Table 2.
The measurement was not influenced by any external factors, such as direct sunshine affecting the heat flow meter, air movement in the room caused by ventilation or air conditioning, movement of persons near the cooling box, heating of the room, etc.
These factors would then significantly affect the heat flow value, which has a substantial influence on the resultant value of the thermal conductivity coefficient of the material measured.
The experimental research of textile fibres implies that the textile fibres feature very good thermal insulating properties.

The preparation, mechanical properties, grain size and thermal property of bulk nanocrystalline Cu (BNC-Cu) were investigated in this paper.
However, many properties and related mechanisms of nanocrytalline materials are also not understood, especially the mechanical properties and related deformation mechanism of nanocrystalline materials, which are mainly caused by the lack of bulk nanocrystalline materials with 100% theoretical density.
The preparation, mechanical properties, grain size and thermal property of BNC-Cu were investigated in this paper.
The minimum grain size of Cu and the relationship between the grain size and ball milling time are related to many factors in the ball milling system, such as ball milling energy, physical properties of elemental metals and ball milling temperature.
In the process of ball milling, the hardness of Cu is synchronously affected by hardening effect and softening effect.

Adhesion strength is provided by a number of other factors, including the diffusion of the coating components into the base material, fusion and chemical compound.
However, pretreatment of the base surfaces remains an important factor for ensuring the adhesion strength of the applied coating with the part, since in most cases, the connection of the sprayed coating with the basis occurs as a result of mechanical clutch.
The use of thermomechanical treatment of preformed coatings (applied by gas-thermal spraying) makes it possible to increase the adhesion strength of the coatings with the base while preserving the original structure and properties of the powder as much as possible [16].
Theoretical Part Analysis, justification and development of recommendations on the use of methods for testing mechanical properties of materials, including composite ones, obtained by methods of gas-flame spraying of coatings, is one of the most important stages of the study, which allows not only objectively judging the mechanical behavior of parts during operation, but also actively to manage the resource of their work, affecting the composition, structure, properties and technology for producing coatings.
The adhesion strength of coatings with the base metal is one of the important factors characterizing the possibility of using metallic coatings.
