Therefore, it is necessary to improve the mechanical properties of 800H.
On the other hand, the welded joint is also a key factor for controlling the properties of the heat pipe stream generators.
Then, microstructure characteristicsand mechanical properties of joints were investigated comprehensively.
Tensile properties.The room-temperature and high-temperature tensile properties of dissimilar welding joints were measured, respectively.

Presence of this phase leads to the mechanical and physical properties of the alloy reduce [5].
The graphs are constructed from the average values of five measurements of mechanical properties.
Such dependences of the mechanical properties are observed for a thickness of 0.25 mm and for a thickness of 0.33 mm.
An experimental evaluation of the surface roughness of a sheet of an aluminum alloy AA6022 with a multi-cycle tensile and compressive plastic deformation [15] showed that the texture, direction of the test and degree of deformation of flexure/extension are significant factors affecting the surface roughness of the product after bending.

Buildings are a crucial part of our daily life, on average people spends 85 % of their time performing activities inside of buildings and therefore the quality of the indoor environment is a critical factor affecting the happiness and productivity of building users.The indoor environmental quality has a strong relationship on the thermal conditions of a space which is directly affected by the amount of heat lost or gained due to the properties of the materials used, the external environmental conditions and the inner sources of heat; In consequence, efforts have to be made to maintain proper thermal conditions by means of using natural and mechanical strategies to provide heating, cooling and ventilation.
When these factors are known, the thermal sensation for the body as a whole can be predicted by calculating the predicted mean vote (PMV) using the following formula: where: isthe Metabolic rate, .
It is the effective mechanical power; is the Clothing thermal resistance, .
The sources of heat that affect the room environmental conditions are mainly related to the amount of heat produced by the people in the space.
Air movement Conclusions Although this analysis shows the general thermal behavior during the typical operation of these particular space types, different load conditions may occur from space to space related to the use of different HVAC equipment, lighting fixtures, constructions materials, space arrangement, occupancy rates, electrical equipment, outside weather and climate factors, among other loads,which lead to major changes in thermal comfort parameters.

A Brief Review of the Modelling of the Time Dependent Mechanical Properties of Tissue Engineering Scaffolds N.
While the former drives a mechanical property decline in the scaffold occupied regions of the construct, the latter tends to increase the mechanical properties of the porous region.
Models of the Mechanical Properties of Tissue Scaffolds Models of tissue scaffolds take in as input the various chemical, material, and geometric parameters of the tissue scaffold, such as pore geometry, crystallinity, molecular weight, and the mechanical properties of the scaffold material, and give as output the effective mechanical properties of the tissue scaffold.
