The garnet structure is responsible for a number of specific features in the behaviour of the magnetic, magnetoelastic, and magnetooptical properties of these compounds, which qualitatively differ from those of crystals with cubic symmetry of the environment of the magnetic ions.

W in the NiW coating forms definite compounds with the refractory elements of the superalloys.
The size of these compounds increase during service by dissolution of alloying elements and coalescence to slow down interdiffusion kinetics.
The nominal composition of this alloy developed by ONERA [6] is given in Table.1.
The DB limits some alloying elements diffusion from the substrate to the surface, especially Cr and Ru. 7.

The aluminum scrap of 6xxx series alloys was collected from a machining workshop in Norway.
It can be seen that the scrap sample from the workshop contains different aluminum alloys (Fig. 5).
This heterogeneous characteristic of the present aluminum scrap, i.e. mixture of aluminum alloys, results in obvious challenges for the solid state recycling process.

The present study aims to investigate foamed alloy deformation and examination of compressive response of aluminium foams created via a melt process similar to AlporasÒ route being realized with the usage of calcium carbonate CaCO3 as blowing agent by employing relatively ductile and high strength aluminium alloys.
The density of the parent alloys was of 2.7 g/cm3 and 2.8 g/cm3, respectively.
Not less than three samples of each solid alloys were tested under compression.

Producers of secondary raw materials composed of salts, halide compounds and oxides are metallurgical enterprises, including those producing aluminum and silicon.
The composition of melted alloys, the furnace gas cleaning technology and the exhaust fume capture technology influence the properties of waste products.
The TIG welding makes it possible to obtain high quality joints from steels of various grades, including high-alloyed ones, as well as non-ferrous metals and their alloys [17-25].
The third composition - nanosilica – was composed of silicon compounds of an ultrafine fraction with a particle size of 40-80nm.

The aim is to identify simple and cheap methods of production that can enhance the mechanical properties of aluminium alloys for hydro turbine blade production.
Aluminium deposits are vast in sub-Sahara Africa and their alloys can be sourced locally.
This process involves the following steps: production of powder metal, metalloids, metal alloys or compounds; blending and mixing of powders, compaction; sintering; and, in some cases, repeating the operation [9, 28, 29].
The method is used in the casting of metal such as functionally graded materials (FGMs), alloy steels, corrosion- and heat-resistant steels, aluminum alloys, copper alloys, etc.

The light blue region shows the not fully reacted region where a highly defective Ni-Si-C alloy is predicted by the simulation.
The compound fraction is normalized to the total Ni content in the film.

We envision that Environment-Enhancing material science and technology should be explored aiming at meeting our entire fuel need, achieving net-zero carbon emission and water use, and recycle the nutrient in the feedstock.
In "Study on Preparation of a High-strength and High-toughness Low-alloy Steel for Cross Member of Forklift Mask", Yi designed a new type of high-strength and high-toughness low-alloy steel by multi-element alloying.
In "New High Strength and Heat Resistance Aluminum Alloy Material for Engine Cylinder Head", Li and Su studied the effect of Cu、Ni、Fe、Mn on the mechanical properties of Al-Si alloy by orthogonal experiment method.
The ratio of Fe and Mn was controlled to prevent the appearance of β phase, and reduce herringbone Fe phase.The best content of Cu、Ni、Fe、Mn was obtained, which improved high temperature strengthening of the alloy.
In biomaterials field, Liu compared solvent-casting and melt-compounding blended polylactide-polyethylene glycol mixture as drug carrier.
