The aim is to get the microstructure evolution law of reheating hypereutectic Al-Si alloys after adding Fe and Mn.
Nevertheless, the studies, aiming at microstructure evolution law of reheating hypereutectic Al-Si alloys after adding Fe and Mn, is still insufficient.

JILM was launched in 1951 aiming to promote science and technologies of light metals and to develop light metals industry.
Nano-hetero structure alloys The Fe contained in aluminum as an impurity element produces coarsened and irregular shape intermetallic compounds preferentially and normally affects extremely reduced mechanical properties, especially ductility.
The corrosion resistance also decreases by large Fe containing intermetallic compounds (Fe-IMCs).
If Si is not contained the binary Al3Fe compound is also produced.
These Fe-IMCs are harmful for aluminum alloys.

A selective Cr depletion was observed to weaken the stability of the passive film on the alloys.
This work aims to look at an electrochemical interaction of lead on Ni-base alloys and Ni, Cr as a function of the solution pH and lead concentration.
It seems that an increase of the anodic peaks promotes a SCC of the alloys.
This result is caused by the Ni itself or Pb compounds deposited during the initial delay before the anodic scanning.

This study aims to characterise the mechanical properties of Al-Si-Cu-Mg alloys at ambient and elevated temperature in the presence of different content of Mo.
For this study, a single step solution treatment at 525 °C for 20h was considered for all alloys in order to increase the possibility of dissolving Mo-bearing compounds.
EDS analysis showed two major Mo-containing compounds in the alloys with Mo; AlSiMo and AlFeMoSi as their attendance were also pointed out in other studies [21, 22].

In this paper is presented an experiment whose aim is to determine the cutting forces that appear when machining Ti6Al4V titanium alloy, in order to optimize its working rate and productivity.
Titanium alloys are a continuous challenge.
Not to be forgotten that even the price of titanium and titanium alloys is high, the advantages of their use are considerable.

Introduction Silicon is significant alloying element in aluminum alloys, which improves the fluidity and mechanical properties of Al-Si casting alloys and forms disperse precipitate particles to enhance the strength and toughness of Al-Si-Mg wrought alloys [1-2].
In this aspect, compound method which adds alloying elements to form Si-rich compounds in liquid metal was researched.
For example, calcium was chosen to form compounds containing silicon, Ca2Si and CaSi2Al2, which were separated from Al melt by filtration [5].

Zinc-based alloys were thought to be attractive substitutes for copper alloys in many structural applications[3].
Zn-Cu-Ti (ZCT) alloys have also attracted many efforts since 1940’s.
The aim of the present work was to investigate the effect of deformation parameters on the flow stress of Zn-8Cu-0.3Ti alloy and establish the flow stress model.

Some are used as solid solution strengtheners, while others are added because they form various desirable intermetallic compounds [3].Aluminum alloys containing silicon as the major alloying element offer excellent castability, good corrosion resistance, and can be machined and welded [4].
In this family of alloys of hypoeutectic compositions strengthening of Al-Si alloys is achieved by adding small amounts of Cu, Mg or Ni. [5-7].
The various heats of this alloy were prepared using Al ingot and different master alloys.
Sometimes the salts also cause porosity in the solidified alloys.

The machining process of titanium alloys always need special control by using coolant and lubricant as it is one of the difficult-to-cut materials.
At same times, titanium alloys are recognized as a difficult-to-cut material [1-8].
However, some of them, especially extreme pressure additives, contain Cl, S or P compounds which endanger to environment and people health.
There are many methods to deal with the machining problem of titanium alloys, although it belongs to difficult-to-cut materials [8].
The cutting temperature of titanium alloys is much higher than that of C45 steel, which is another machining character of titanium alloys.
