At this process condition, the alloy had an excellent comprehensive mechanical properties and conductivity property of the tensile strength, elongation, and electrical conductivity reaching 549MPa,15% ,and 82.34%IACS respectively.
In order to obtain better mechanical properties, cold working and heat treatment were both used for the alloy.
When the temperature is below 460℃，the precipitation particles is the main influencing factor, the hardness of alloy increase. when temperature is higher 460℃, recrystallization is the main influencing factor, the alloy hardness decrease.
However, the reason of different properties of four alloy aged at different temperature is reply recrystallization.
At this process condition, the alloy had an excellent comprehensive mechanical properties and conductivity propertyof the tensile strength, elongation，hardness and electrical conductivity reaching 549 MPa,15％,82.34%IACS and 215HBW respectively

Strain rate, strain and temperature are reported as the main factors affecting DRX [4].
The mechanical properties were evaluated by tensile testing and micro-Vickers hardness testing.
Table 2 Mechanical properties at room temperature.
The mechanical properties obtained at different extrusion conditions are shown in Table 2.
Fig. 6 shows the effect on mechanical properties of preceding T6 temper by an annealing run: The Vickers hardness of the T6 temper increased by 10 HV.

Except under the control of the geological conditions, the inducing factors of all kinds of landslide was mainly affected by rainfall effect and human engineering activities [1].
The landslide is in the left bank of Gao Lan river in three gorges reservoir area of HuBei province, the landslide is in basically stable state at present, but the landslide may lose stability under the heavy rain, once the landslide occurs, it will seriously influence the learning, living ,life and property security of more than 100 teachers and the students in the school in the leading edge of the landslide firstly; it seriously threaten people's life and property security in front of the landslide secondly ;it seriously affect the safety of S312 provincial highway and the people passing by thirdly, so the stability analysis of the landslide is very important.
Therefore, the landform is a important factor for the landslide to form.
Based on the " Code for investigation of geotechnical engineering " (GB50021-2001)[7], this paper using transfer coefficient method to calculate the stability factor and surplus sliding force.

Weathering can cause discoloration, chalking, dimensional change, and loss of mechanical properties of wood-polymer composites.
The weathering, both natural and accelerated, of WPCs can change their colour/appearance [1,2], and mechanical properties [3,4].
The two main weathering factors (water and ultraviolet radiation) affect WPCs significantly.
Fibre swelling due to moisture absorption is primarily responsible for the loss of mechanical properties after weathering [7].
The changes in properties of composites depended on the method of weathering.

The article discusses the features of the casting process of non-ferrous metals, the basic properties of various alloys, affecting the appearance of various defects of the resulting casting.
The proposals to improve the efficiency of the casting of non-ferrous metals in metal molds and specific recommendations for improving the performance properties of metal depending on the melt being poured are given.
It is explained by several factors, one of which is high physical and chemical activity of aluminum alloys, proceeding from it, forms have to possess a protective layer, or special lubricant, otherwise, aluminum diffused in a blanket of form-building details, worsening thereby plastic and mechanical properties [4].
The specified factors will allow to reduce the size and amplitude of fluctuations of the stretching tension in form-building details, both in closed, and in the opened condition of a compression mold that will allow to increase the period of work of a compression mold until formation of cracks of the I type.

The results of the research are the obtained mathematical models that can be applied to analyze the influence of individual factors, as well as their combination on the quality indicators of the process of forming coatings with given physical and mechanical properties.
To solve this problem, studies have been carried out, the purpose of which is to develop a multicriteria model of technological processes for applying composite materials and optimizing the modes of their formation with the possibility of obtaining plasma coatings with specified physical and mechanical properties.
A total of 32 experiments were carried out for one series, since 5 factors were taken, changed at two levels.
The resulting coatings were compared in terms of their emission properties with cathodes, the coating on which was obtained by conventional methods. 2.
Investigation of the properties of plasma coatings based on the use of regression analysis.

The results indicate that when the ratio of soft and hard monomer is in the range of 1:1~2:1 and the amount of cross-linking agent is added, the comprehensive properties of acrylic emulsion are good.
During this process, effects of the ratio of soft and hard monomer and the amount of cross-linking agent on emulsion properties were discussed.
Under a given set of other factors, different ratios of soft and hard monomers were changed (Table 1) and then a series of polymer emulsion with core-shell structure were synthesized.
When the ratio of soft and hard monomer is in the range of 1:1~2:1 and cross-linking agent is added, the comprehensive properties of acrylic emulsion are good.
The ratio of soft and hard monomer and cross-linking agent can affect the performance of coatings.

This approach enables a significant enhancement of the mechanical and performance properties of concrete, including improved tensile strength, crack resistance, and fatigue durability.
The use of fibers as an element of dispersed reinforcement significantly improves the mechanical properties of concrete, particularly by reducing brittleness, which is typical for cement stone.
The variable factors were: the content of polypropylene fiber (PF), kg/m³ (X1 = 2 ± 1 kg/m³), and content of steel fiber (StF), kg/m³ (X2 = 80 ± 40 kg/m³).
