This paper aims to present the effect of powder particle size of Tin Based Alloy sintered using different type of heat source.
However, it was noted that in a powdered form, all metals, alloys or intermetallics will couple in a microwave field efficiently and effectively to produce highly sintered bodies with improved mechanical properties [10].
The Bragg angle and the values of the interplanar spacing (d) obtained were subsequently matched with the standard values for Sn, Cu, Sb and their intermetallic compounds.

The effects of flux components and compositions of solder alloys on the wettability of the Sn-Zn alloys on aluminum surface was investigated.
Experiment Sn-9Zn alloy, Sn-9Zn-x Bi alloys, Sn-9Zn-x Sb alloys and Sn-9Zn-x Al alloys have been prepared from the pure metals (Sn, Zn, Bi≥99.95wt% and Al, Sb≥99.5wt%).
In this paper, 13 kinds of alloys were designed as listed in Table 1 aim to study the effects of Bi, Sb, Al on the wettability of Sn-9Zn solder on aluminum substrate respectively.

It is an effective way to improve properties of solder alloys by adding foreign minute dispersoids [6-11].
However, if the amount of intermetallic compounds are over, the wettability of the solder alloy maybe deteriorated.
From Fig.7, the intermetallic compounds (Cu6Sn5) between the solder and the Cu substrate increased with the increase of Ag content.
This is because Ag particles help to form the intermetalic compounds Cu6Sn5 between the substrate and solder alloy and improve the wettability of the composite solders.

However, severe plastic deformation of magnesium alloys is more difficult to implement than in aluminum alloys due to their hexagonal lattice and hence a limited number of slip systems and resultant formability [7, 8].
The common feature of above studies is that the ECAP process was applied to magnesium alloys in as-cast state.

Ceramic coatings consist of α-Al2O3 and γ-Al2O3 predominantly with little Al-Si-O compounds known as mullite.
The Al peak increases firstly and decreases afterwards, suggesting lots of Al change into Al2O3 and other compounds with Al.

The catalysts are aimed to be used as anode in alkaline fuel cells.
According to the SEM results, both compounds were formed in nanosized particles and BET results showed that BET surface area of V0.3Mo0.7O3 catalyst has 5 times higher than that of V0.6Mo0.4O3.
This study aims to give a quick report about the potential of the vanadium molybdenum mixed oxides to be used as catalyst in the fuel cells.

In the present study, aim to preserve the high quality and depress the fabrication cost of the brazed tools, the powder mixture of Ni-Cr-B-Si alloy is introduced and the corresponding brazing experiments are conducted via laser brazing so as to detect whether or not the powder mixture is applicable to join Diamond and medium carbon steel substrate.
Before brazing, the Ni-base powder mixture was alloyed during the heating process, and XRD result in Fig.1 indicates that the special element Ti of the powder exist in a compound form.
Microstructures of the formed compounds in the interfacial region and EDS analysis of the compounds.
In the interfacial reaction region of the diamond grains and the filler metal, the chromium in the Ni-based alloy segregated preferentially to the surface of the diamond, and Cr-C compounds is formed, through which good joining are accomplished between the filler metal and diamond grains. 2.

The aim of the paper is to study an influence of low energy ball milling on structural and magnetic properties of (Fe80Nb6B14)1-xTbx (x = 0.08, 0.12) bulk nanocrystalline alloys.
The phase analysis reveals a presence of the main two magnetic compounds i.e. magnetically hard Tb2Fe14B (tetragonal structure) and relatively soft TbFe2 (cubic structure).
The detailed phase analysis of the examined bulk alloys is presented in [5].

Introduction The aim of this work is to obtain metallic alloys with high mechanical strength and high electric conductivity after adequate optimization of sintering and thermal treatments followed by structural, microstructural, electrical and mechanical characterization of Cu-y%Ni-x%Al alloys (where x and y are variable values).
The alloys elements are added to copper aiming at improvement of the resistance mechanics, ductility and thermal stability, electrical and thermal conductivity, beyond resistance to the corrosion.
Thus, beyond the studies of the mechanical and structural properties, they had been initiated measured of electric conductivity to the temperature of 293K, 273K, 195K and 77K aiming at a prospection of these properties in CuNiAl alloys obtained by powder metallurgy.
