Introduction Superplastic forming and forging have now become an important industrial means for the fabrication of workpieces with complex shapes from advanced metallic materials.
Experimental Materials and Methods The experimental materials are forged block of 1933 aluminium alloy with the chemical composition of Al-6.42Zn-1.63Mg-0.97Cu-0.12Zr-0.023Mn-0.11Fe (all in wt%).
Annealing at 400 ºC for 1h is as the other method to refine grain of original material.

During a laser pulse, several competing interactions affect the material.
Comparison between 102 and 105 Monte Carlo steps (MCS) on the stage of linear cooling down of the material (phase 2.)
As showed in [10, 11], the MSC can be mapped to real time and depend on R and the physical properties of the material.
Summary We studied the FePt L10 ordered granular material using both atomic and macrospin approaches.

Thermal actions change the physical-mechanical and thermal characteristics of the materials and provide appropriate conditions for some phenomena to occur, which can have negative effects on the performance of the structural element, in particular spalling.
In the case of CFTC elements the outer boundary of the section is characterized by high thermal gradients, which unleash a series of phenomena at the interface of the concrete and steel profile, which affect the bond between the two materials and have a negative effect on the structural performance of the element.
With the development of new construction materials with high fire resistance and innovative new technologies, the issues regarding thermal exposure may be avoided, yet the problem remains in the case of existing structures.
In the present study, the discontinuity between the surface of two solid materials is modeled through a radiative heat flux.
The present values have been extracted from the datebase of the materials.

In the present study, loquat of Guangdong province was selected as experiment material and investigated in order to analyze the effect of GA3 on storage quality and nutrition components of loquat fruit, aiming to provide foundations for loquat production and its post-harvest preservation and storage.
Materials and Methods A.Experimental materia Loquat from Chaoan country in Guangdong province was used as experimental material in the present study.

Dynamic Similarity of Wind Turbine’s Tower-nacelle System and its Scaled Model Jacek Snamina*, Paweł Martynowicz*, Waldemar Łatas** AGH University of Science and Technology, Department of Process Control, al.
Diagram of the model Kinetic energy of the beam with attached solid body may be described in the following form: (2.1) where is the density of beam material and is the mass of solid body.
As a result, the similarity conditions were obtained, that have to be fulfilled by the introduced similarity scales factors, the geometrical parameters, and the material properties of full-size object and its model.

Material Sample.
So their homologies were very well likely because the soil samples had the same parent material, rock or similar soil chemical process, and they were more likely to take on combined pollution.

The results of comprehensive quality index evaluation method of Water quality showed that four reef site index is greater than 1, in the slight pollution levels. so it indicated that this sea water, especially reef site still exists the risk of contamination, Except considering the external environmental factors, It is important to examine whether the reef itself have lasting impact on the environment or not, so as to gradually improve and optimize the design of the reefs and materials.
