Also, with an increase in the number of rare-earth metals in an aluminum alloy, the number and size of intermetallic compounds increases with the classical methods of preparing the ingot, which negatively affects all the properties of the wire.
Annealing the wire in 4 modes does not lead to visible changes in the size and shape of the particles of intermetallic compounds.

Introduction Titanium alloys are widely used in the aerospace, nuclear, chemical, biomedical industries and so on, due to their excellent combination of low density, high strength to weight ratio, excellent corrosion resistance and biocompatibility [1-6].
At same times, titanium alloys are recognized as a difficult-to-cut material [1].
However, some of them, especially extreme pressure additives, contain Cl, S or P compounds which endanger to environment and people health.

So, NbC/VC based WC-8%Co alloys are worthy of study in the present research.
A small quantity of VC (0.4% by weight) and NbC(0.4% by weight) was added to WC-8% alloys.
The solubility of WC in the binder Co is 40% of that in the WC–Co alloys.
However, according to VC, the solubility of WC in the binder Co drops to 10% in the WC–Co–VC alloys [16].

Foreword The DX center is a defect present in Gallium Arsenide and related alloys when these materials are doped with n-type impurities.
The understanding of the physical processes which lead to its existence will allow to select the alloys (nature, composition and quality - ordered or disordered) and the new materials, such as superlattices, to be used in devices.
However, the numerous presentations which are currently made at various international conferences (on GaAs and related compounds, semi-insulating III-V materials, etc.), probably because too often given by same group, do not reflect this trend.
However, the book does not contain general reviews on GaAs and GaAIAs because recent, excellent ones already exist in the Journal of Applied Physics by J.S.
In conclusion, the book is intended for the specialists who study or use GaAs and related alloys.

The quenching is one of the most used mechanisms for increase the strength of aluminum alloys sheets.
Introduction The typical heat treatment for heat treatable aluminum alloys is the solution heat treatment at around 500 °C (the temperature being very close to the melting point of each alloy) to ensure that all hardening compounds are dissolved in the solution [1].
Water is the most widely used coolant for all aluminum alloys.

The aim of the present work was to obtain nanostructured aluminium/precious metal oxide composite materials with high specific strength via MA of pure aluminium powder with additions of AgO, PtO2 or PdO powders followed by SPS.
The formation of the above compounds at progressively increasing heating temperatures was accompanied by a rather steep decrease in hardness from peak value (see Fig. 1).

However, the corroding rate of Mg alloys is too fast to satisfy mechanical integrity before the tissue has healed, which limited Mg alloys using as biodegradable materials in the orthopaedic and cardiovascular applications.
To explore a novel and more practical route for possible large-scale application of metal matrix composite (MMC) based on Mg alloys, the use of reinforcement to improve mechanical and corrosion properties in Mg alloys is considered.
Little is known of the effect of ceramic particles on the microstructure of Mg alloys.
By XRD analysis, the microstructure of Mg-Zn-Zr alloy consists of Mg matrix and eutectic compounds.
These high impacts can lead to strengthening and toughening of Mg alloys.

Recently, most of the implant materials used in orthopedic surgery are made of titanium alloys.
However, at certain temperatures, HA can decompose partially to form other compounds.

Next, the CuCr2-xSnxSe4-compounds were manufactured from obtained binary selenides: CuSe, SnSe and Cr2Se3.
The sintered compounds were again crushed into a powder and used for structural studies.
Measurements of compounds were made at magnetic field 0.5 T.
