After deposition, the films were heat treated, aiming to crystallize and stabilize the zirconia cubic phase.
One of the great advantages in the operating temperature reducing is the possibility of the use of more conventional steel alloys as interconnectors at temperatures around 700 °C [[] L.

Addition of strontium has been considered as the potential choice for heat-resistance AE series alloys due to the formation of highly stable intermetallic compound.
It demonstrates that the AE42 alloys are mainly composed of α-Mg, β-Mg17Al12 and Al-RE compounds.
With addition of strontium, the AE42 contains α-Mg, β-Mg17Al12 and Al-RE compounds besides new secondary phase Al4Sr.
Because of the high chemical stabilities of Al-RE compounds and Al4Sr, RE and Sr are combined with Al and formation Al-RE compounds and Al4Sr without any generations of ternary phases Mg-Al-RE phase and Mg-Al-Sr phase until all the available RE and Sr are used.

FSW was applied to the Al alloys by the weld zone phenomena at the newly invented stage.
This study was aimed to evaluate the joint characteristics of the Mg-Zn-Y alloys using FSW and acquire the optimum welding conditions.
The particles are analyzed as intermetallic compounds of the Mg6Zn3Y1, which represented some compositional change compared to I-phase reported by BAE et al..

The aim of this paper is to find suitable process parameters to infiltrate the porous copper inlay with the semi-solid aluminium alloy during thixoforming.
Aim of the produced compounds is the infiltration of the porous copper inlay with semi-solid aluminium, while reducing the growth of intermetallic phases by varying process parameters.
Furthermore, microhardness measurement were conducted in order to characterize the different Al-Cu phases in the produced compounds.
Thus, the intermetallic phases of Al-Cu compounds tend to be brittle and can crack during cooling due to different shrinkage of the materials.

These were analyzed to consist of eutectic phase Mg-Zn and intermetallic compounds of Mg-Zn-Nd at the grain boundaries and fine Mg-Zn intermetallic particles in the matrix.
The microstructure of the alloy B is shown in Fig.1(b), which reveals that the above mentioned eutectic phases and intermetallic compounds have dissolved into fine intermetallic particles and the grain boundaries become thin a little.
On one hand, the intermetallic compounds become more dispersed, the time when peak hardness occurs is much in alloy B.

Therefore the aim of the present work was to understand the influence of the alloying elements Mg, Fe and Mn in AlSi10 casting alloys on the impact energy properties related to heat treatment and microstructural observation.
A typical hypoeutectic microstructure includes Al-matrix phase, AlSi eutectic phase and particles of the intermetallic compounds, which were reported to be Fe-containing phases due to the secondary alloying elements, can be seen in these alloys.
In the as-cast state for different alloys, the AlSi eutectic phase of thin fibrous and the large particles of the intermetallic compounds mainly exist between the α-Al grain boundaries or the dendrite arms.

The aim of this study is testing and evaluation of Mg-1Ca alloy from biocompatibility in vivo point of view.
Biodegradable is the ability of a material to be chemically decomposed or degrade into compounds under the influence of biological factors.
Biodegradable implant must be absorbed gradually, maintaining mechanical properties until they are no longer needed and then to be absorbed without leaving remaining compounds in the body [2].
