The results indicated that TKCE50 had not only good welding technological properties, but also super work-hardening effect and perfect impact wear-resistance.
Through a series of experiments and on-the-spot application, the electrode was indicated that it not only had good technological properties, but also super work-hardening effect and perfect impact wear-resistance.
Therefore, the mechanical properties of this electrode are very good.
In view of these factors above, the slag system CaO-CaF2-SiO2 was selected [1].
(4) Based on analysis of the performance of TKCE50, its work-hardening mechanisms were found mainly relating to the high density dislocations and twins formed during impact and abrasion tests, which affected the slipping of crystals.

The optimum set of factors (mass of the shot, volume of the chamber and strip-sonotrode distance) that maximise the Almen intensity was found.
The changes in surface layer properties were characterised using roughness, microhardness and residual stress measurements.
Table 1 summarises the studied factors on TiAl alloy with two different experimental levels.
The resulting factors observed are the residual stress profile (maximum stress, depth of the maximum stress, depth affected by shot peening), roughness and microhardness.

Polymeric membranes, while possessing excellent separation properties, are mostly lacking in this area.
The interplay between MMA concentration and radiation dose has not only affected the degree of grafting but also the membrane properties.
Despite having chemically resistant properties, PI membrane performance in specific organic solvent environments can be affected by chemical interactions.
By adjusting factors like radiation dose, exposure time, and monomer concentration, it is possible to precisely tailor the degree of grafting and the properties of the grafted layer.
The objective of this study is to investigate the effects of radiation dose and monomer concentration on the degree of grafting and physicochemical properties of PI-graft (g)-PMMA membranes.

When an external stress is applied to the ferromagnetic material, its magnetic properties will be altered, which is called the magnetomechanical effect [1, 2].
For the passed few decades, a lot of researches have been focused on the effects of stress on magnetic properties, a number of magnetic techniques for NDT have been suggested, developed, and utilized in industry, including both active magnetic techniques and passive magnetic techniques [3-11].
If this contact is not properly dealt with, the change in magnetic properties for sample may in fact be caused by a systematic measurement error, rather than microstructure or stress effects [18].
Also, many other factors can influence the measured precision and reproducibility in magnetic stress measurement.
Therefore we had to taken a corresponding measure to reduce the effects of interfering factors.

Elastomers are crosslinked polymer chains that have elastic properties and liquid crystals are mesogenic materials that have orientational order properties, so LCE have combination properties of both substances [1-5].
If the deformation factors associated with the order parameter of the components of swollen LCE, and, and the volume fraction of LCE,, then the elastic free energy can be expressed by: where and .

There are many factor can caused pitting corrosion such as chloride, pH and oxygen (it may cause the formation of oxide at the pitting and lead to damaged passive film).
Experimental Procedure Corrosion attack may have influence to metal’s properties.
Increasing temperature affects the kinetic of the corrosion process but does not appear to change the corrosion mechanism.

Introduction The search for alloys with improved high-temperature specific strength and creep-resistance properties for aerospace applications has led in the last decades to sustained research activities to develop new alloys and/or improve existing ones [1].
There are many factors that affect the characteristics of creep of metals.
The goal of heat treatment is to change the mechanical and structural characteristics of materials in each application [7].
However, the affinity by oxygen is one of main factors that limit the application of titanium and its alloys as structural material at high temperatures [8].
To consider these interactions the designer requires a description of both the physical and mechanical properties of each layer of the thermal barrier coating [12 - 15].

To prevent this phenomenon, the scaffolds need to be modified in order to provide antibacterial properties.
To overcome this problem, the researchers developed scaffolds provided by antibacterial properties.
Zinc oxide was chosen due to its superior properties compared to other antibacterial agents in which zinc oxide not only provides antibacterial properties but also promotes the growth and attachment of new bone cells [8].
The Effect of Zinc Oxide on Antibacterial Properties of Scaffold Antibacterial activity testing conducted to find out if there were antibacterial effects produced by scaffolds with the addition of zinc oxide.
