In general, castability of magnesium alloys is comparable to aluminum alloys.
The AZ91D alloy is one of the most popular magnesium casting alloys.
Microscopic examination of folds in the AE42 castings revealed a band of intermetallic compounds on either side of the fold, as seen in Figure 2b. 2 cm (a) Subsurface folds (Bright Field, 50x).
Close examination of the band of intermetallic compounds decorating the fold boundary revealed the presence of fine particles (Figure 3b).

The aim of this work is first the elaborations and characterization of the compacts of sintered copper alloys.
The dimensions of the samples after sintering have a linear shrinkage in both directions of the order of 7 to 9% for the alloys (Cu-Sn) and 18 to 21% for the alloys (Cu-Co). 3.3.
Fig.8 recapitulates the variation of density with the variation of the pressures for the sintering temperature (275 ° C for the Cu-Sn alloys, 950 ° C for the Cu-Co alloys).

However, Al-Si alloys are the most common alloys and commercially available ones due to their economical production.
This project aimed to synthesize Al alloys (LM-6, LM-25 and LM-30) by melt stirring method with varying amount of grain refiners and / or modifier.
Recently, much attention has been given to unmodified cast alloys, especially to hypereutectic Al–Si alloys.

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].

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.
