This paper aims to provide theoretical and experimental basis to research and develop magnesium alloy with good integrated mechanical properties.
The size of α-Mg grain has become smaller in the alloy with 0.25wt% Si, large Mg2Sn phase at the grain boundary exists mesh broken phenomena, in addition, Chinese-character-like compounds gather in the forefront of liquid phase in the alloy.
As Si content increases, α-Mg grain becomes more refined, the quantity and size of Chinese-character-like compounds increase, and alloy organization becomes more refined.
As Si addition increases to 0.75%, Chinese-character-like compounds become fine and dispersed, and alloy organization becomes more refined.

The XRD results revealed TiB-TiB2 biphasic B-Ti compounds layer formed on the surface of TC4 after RE-boriding.
Introduction Ti-6Al-4V (TC4) is the most widely used titanium alloy in the aerospace industry, with the occupation ratio of more than 50% of the total titanium alloys [1-2].
As Al atoms can not dissolve in the boride compounds, so the content of Al on the boride layer is only 0.035% (in mass percent concentration).

Moreover, Al alloys have relative good workability and excellent corrosion resistance so that the lightweighting of the body using Al alloys has attracted attention.
However, since the manufacturing cost of Al alloys is relatively high and the strength and rigidity of them are lower than those of steel, it is difficult to constitute the whole body with Al alloys [1].
The brittle intermetallic compounds layer formed at the joint interface also becomes the problem in the dissimilar resistance spot welding [9].
The thickness of the intermetallic compounds (IMCs) layer formed at the joint interface was also investigated with a OM.
It was confirmed that the reaction layer consists of Fe-Al intermetallic compounds (IMCs) such as FeAl, FeAl2, Fe2Al5 and FeAl3.

Some researchers dedicated their work for visualizing the microstructure obtained during the linear FSW of aluminium alloys [6,7].
As the welding is bimetallic, there is formation of intermetallic compounds at the interface aluminium-steel around the hanging.
It has been found that the more the dwell time is high, the more the hanging is wide, but also the more there is presence of intermetallic compounds which weaken the weld because of their high microhardness (between 250 and 800 Hv) [8]
- The microstructure of alloys before welding The Al alloy sheets were hot rolled.
But, at the same time, it induces an important formation of intermetallic compounds which weaken the welds.

Surprisingly, scandium increases the recrystallization temperature of aluminium alloys to above 600°C, well above the temperature range of heat treatable aluminium alloys [2].
The age hardening effect shown by the alloys are purely due to addition of scandium.
Therefore, this work aims to investigate the optimum amount of scandium to benefit the mechanical properties of A356 aluminium alloy.

Thus, the aim of this study is to investigate tensile properties of Sn-5Sb and Sn-3.5Ag-0.5Cu-0.07Ni-0.01Ge alloys using miniature size specimens which have microstructures similar to real solder joints [17-19].
For elongation, a similar tendency was observed in both alloys.
In Sn-5Sb, as shown in Fig. 1, the microstructure consists of fine β-Sn phases and fine SbSn compounds.

The aim of this work is to investigate the influence of Nb content and different preparation methods on the microstructure, mechanical properties and phase composition of binary Ti-Nb alloys for biomedical application.
For quenched alloys this requirement is fulfilled if the alloying content is higher than 25 % Nb.
