We have to mention here that neither the microscopic analyze, nor the Roentgen one make evident the presence of the intermetallic compounds Fe-Co.
The probability of forming such compounds is very low, as the electrochemical and geometrical factors, as well as the electronic concentration of Fe and Co are favorable for the forming at high temperatures of solid solutions with high solubility of components.
As per the theory put above and per the mechanism of alloys solidification, the dispersed phase particles with relatively big sizes 5-10µm should be included in the crystals.

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.

Heat 43-1 is not alloyed with titanium and boron.
This circumstance is an illustration of the fact that the increase in hardenability is affected only by part of the boron that is not bound to stable compounds.
Conclusion The presented data indicate the necessity to protect boron from gases dissolved in the molten steel, such as oxygen and nitrogen, in order to prevent the formation of persistent compounds and reduction of the “effective” boron concentration, which increases the hardenability of steel.

The resulting microstructure depends on material’s heat treatment and alloying.
The present paper introduces new procedures aimed at simplifying this process with the use of material-technological modelling.
In high-strength steels, final microstructure and mechanical properties upon heat treatment are dictated mainly by their alloying concept.
To shift the Ms and Mf temperatures toward lower values, high-strength steels are alloyed with molybdenum and manganese.

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 this study is to analyze the influence of interstitial and substitutional elements, in addition to different heat treatments, on structure, microstructure and some mechanical properties (hardness, modulus of elasticity and internal friction) of Ti-15Zr alloys with the addition of different levels of Mo and interstitial oxygen.
The microstructures of alloys were analysed using optical microscopy images.
The aging treatment allowed α phase precipitation in alloys with a low amount of Mo [7].

Recently, the commercial products of NiTi alloys have been dominated largely by medical related products due to its good biocompatibility [1], high corrosion resistance, and lower apparent elastic modulus apart from its unique behaviour of pseudoelasticity and shape memory effect.
While most current application of NiTi is made of conventional alloys in solid forms such as wires, plates and thin wall tubes, keen interest have been given to novel physical forms i.e porous, thin film and functional gradient of NiTi.
The formidable challenge of obtaining single phase NiTi from elemental powders via solid state is the formation of other intermetallic compounds such as Ti2Ni and TiNi3 which may deterioriate the shape memory behavior of NiTi [7].
Therefore, this paper aims to investigate the use of MgH2 in combination with CaH2 as in-situ reducing agent to provide a non oxidizing environment in order to produce single phase NiTi.
