The effect of these additive elements on the solderability, intermetallic compounds (IMCs), and electromigration performance of low-Ag SAC (LASAC) solder were investigated.
The solder alloys investigated in electromigration test are: LASAC, LASAC-0.05Ni, LASAC-3.5Bi, LASAC-3.5Bi-0.05Ni and SAC305.

This mechanical activation is aimed at to synthesize an ultra fine grained TiAl/Al2O3 composite.
In most cases hydrocarbon and /or carbohydrate compounds were used as PCA during milling [2-8].
Therefore, PCA compounds usually can introduce contaminations like O, H and C to the milled powder by decomposition during milling.

Titanium and its alloys are recognized as having low wear resistance.
The paper aims to present a tribological characterization of the sintered TiAl alloy; the method uses the disc of the alloy that has been researched in contact with an alumina ball.
These titanium alloys are generally used in the automotive and aerospace industries, in conjunction with different similar or hard aluminum alloys.

But its poor corrosion resistance has been cited as a potential problem with its use.Nickel phosphorus (Ni–P) alloys systems are very attractive due to their good corrosion and wear resistance behavior.
In particular nickel phosphorus (Ni–P) alloys systems are very attractive due to their good corrosion and wear resistance behavior which make them suitable for important technological applications.
Hence, the present work is aimed to carry out a few systematic studies on the effect of phosphorus concentrations on the electrochemical preparation and characterization of Ni–P alloy films.

The Mg-Gd-Dy-Zn alloys are the typical magnesium alloys with heat resistance and high strength.
In this paper, an dual phase Mg-Li-Gd-Dy-Zn alloy was prepared through cast and extrusion, aiming to achieve excellent comprehensive mechanical properities.
Compared Fig. 6(a) with (b), the ultimate tensile strength and elongation increase, and it is attributed to the finer Mg3X compounds and the formation of a large amount of finer particles after heat treatment.

Typically these intermetallic alloys are susceptible to hydrogen environment embrittlement.
In this process, water vapor in the air induced cleavage fracture of intermetallic alloys.
Nevertheless, one shortcoming with intermetallic compounds as structural materials is that they are susceptible to hydrogen embrittlement environmental which limits their applications [4,5].
Thus, in this paper, we are interested to know the FeAl2 and FeAl3 intermetallic compounds susceptibility to the reaction with water when it is induced in a ball mill.
Both intermetallic compounds are hard and brittle materials and during high-energy ball-milling, their particle sizes are reduced due to continuous fracturing.

In the range of calculated temperature 1000-1600 oC, the three kinds of intermetallic compound phases, α-Nb5Si3, Ti5Si3 and Ti5Si4, have greater ternary solubility, while other binary intermetallic compounds have no ternary solubility nearly.
The calculated results suggested the composition of Nb-Si-Ti alloy should locate in the two phase region of Nbss and Nb5Si3 compounds, which can provide primary theoretical guidance to optimize the compositions of Nb-Si-Ti alloy.

Alloys with two different RE amounts were tested, with compositions Nd17Dy2B12Co8Fe61 and Nd15Dy2Co5B12Fe66.
Different alloys compositions behave differently in carbon presence.
Alloys with higher amount of rare-earths, consequently with more RE-rich phase, showed more tolerance to carbon presence, being less affected by carbon than lower RE alloys.
