The low solubility limit of many alloying elements means that Mg alloys are often multiphase with a Mg-rich matrix and cathodic intermetallic particles.
In contrast, there was more charging for the peaks associated with Mg hydroxide and Mg carbonate; this indicates that these compounds were located in the outer part of the surface layer.
The influence of Al in Mg alloys as an alloying addition on the initial oxidation has been studied for decades.
In the air formed films, the surface layer was a mixture of MgO and Al2O3, significantly enriched in Al2O3, and as separate compounds; they did not form a structural entity.

The present work is focused on one Additive Manufacturing (AM) process – Laser powder Metal Deposition (LMD-p) – and on one metallic alloy – Ti-6Al-4V.
Thus, this paper relates to first manufacturing investigations on small sized specimens (bead, wall and block) with the aim of providing a better knowledge about the first steps of manufacturing.

The displacement of each alloyed giant magnetostrictive material was measured.
Terefenol-D is an alloy composed of terbium, dysprosium, and iron.
Furthermore, a compound of Tb0.27Dy0.73Fe1.95, and carbon was confirmed.
Instead, several compounds containing Tb2Fe17 and carbon were identified.

The aim of this work was the determination of effect of the chemical composition of Li-Na-K of a binder of the electrode coating for welding of high-alloy chromium-nickel steels on the cytotoxicity of WA, which are formed during their application.
Namely these chemical compounds are extremely dangerous (carcinogenic) substances and they determine the value of WA toxicity in this case.
The formation of other extremely dangerous compounds of hexavalent chromium CrO3, except of a moderately toxic trivalent Cr2O3, is also not confirmed.

Other objective aimed to analysize the effect of electroless plating time on the coating performance of SiC powders.
After electroless plating, the compounds was cleaned with de-ionized water at lest five times.
The compounds concluding copper (D50=38.5μm) and SiC powder (D50=89μm) coated copper were mixed to cold pressure (pressure 300MPa) and form block Ф40mm×10mm, then hot pressed sintering (30MPa,760℃, 40min).

A large majority of the reinforcements are either pure metal or intermetallic compounds [1-5].
Addition of micro-sized nickel particles to an Sn-3.5 Ag solder favors the formation and presence of intermetallic compounds around the reinforcing nickel particles [4].
The rational for the observed increase in hardness of the composite solder is ascribed to changes in intrinsic microstructural features coupled with contributions arising from the formation, presence and distribution of second-phase, i.e., intermetallic compounds.

In this work, we have investigated several configurations of Ti-Al-Si based contacts, aiming at favoring liquid-solid reactions and / or Si element diffusion, in order to get better SCR and / or morphology and cohesion of the metallic phase.
For Al/Si/Ti stacking, no binary Al-Ti compound was expected to be formed during annealing while for Al/Si/Al/Ti stacking, no binary Ti-Si compound was expected.
For schemes “S2” and “S3”, (Al1-XSiX)3Ti compounds + Al phases are expected to be formed at equilibrium for the same temperature range 600 - 800 °C.
Therefore, the same compound as in sequence “S2” was not formed.

Main aim of the presented research activities is focused on preparation of biocompatible titanium based materials with controlled porosity.
Introduction The most frequently used biocompatible materials in traumatology are stainless steel and titanium and/or titanium alloys.
Porous titanium and/or titanium alloys represent perspective trend in production of biocompatible materials with elastic modulus similar to the human bones.
The main aim of this paper is development of new method usable for production of titanium specimens with controlled porosity.
