Steelmaking sludge requires preliminary dewatering operations (possibly using lime) whereas slag should be graded according to grain size.
Metallurgical waste utilisation based on substitution of primary raw materials with the secondary ones will lead to reduction of the natural environment degradation, both by limiting the depletion of natural resources, including energy resources, and decreasing the quantities of waste stored at dump sites, and hence reducing the number and size of the dump sites themselves.

Results show different structures depending on the number of cycles / hydrogenation stage.
In addition, the amount of desorbed hydrogen is not only related with the capacity of the hydride; it has moreover to do with kinetics, grain size, possible catalysts added, and also with the way powders are grinded [10].

Because the number of defects declines as the crystallization improves with H+ ions for the crystal structure which boosts the deposition atoms’ mobility.
The scattering mechanisms occurring in AZO films mainly includes the neutral and ionized impurities and the grain boundaries scattering.

Adhesion Tests. fix 3＃Zahn to the incision and open, observe the lattice region, with the remaining lattice number, evaluation ink adhesion, expressed as a percentage.
Resin R2 produces smaller particle size and more uniform distribution, 95% of the ink particle size is 0.571μm; while resin R3 results in larger ink particle size and uneven distribution, 95% of the grain size is 1.595μm.

Due to the above an increasing number of vessels (i.e. so called ‘Bumerang’ ferry) is built from light aluminum alloys such as 5xxx series and 7xxx series.
Titanium content in the SP20 binder permits to obtain, during welding, low grain size structure, which results in good mechanical properties of the welded joints of 7020M alloy.

It defines the damage variable D as the ratio of cycle number n under a cyclic load and the material’s fatigue life under the same load, it is denoted as
Grain size effect on the small fatigue crack initiation and growth mechanisms of nickel-based superalloy GH4169.

This microstructure is probably a consequence of aluminum grain orientation, preferred dissolution planes and secondary phases distribution that promoted local acidic etching and causing the dual micro/nano-scale structure on the aluminum surfaces.
This implies a high number of similar peaks very close to each other.

The processes of mechanoactivation can cause the appearance of metastable phases with a typical nonstoichiometry and diminished grain size and impurities of technological origin.
The number of incident beam particles reaching the sample was measured with an accuracy of ~1% using a secondary monitor.

Spray paint, fine grained sand, permanent markings and glass beads were all considered, with the 0.5mm glass beads chosen due to its preferable size (being able to be detected by image analysis) and uniformity.
Manual tracking software could be implemented to track the single particles not identified by Multi-Tracker however depending on the number of particles detected this could laborious to complete.

The mixture was constructed according to the Andreasen particle packing method with a coefficient q = 0.25, with a maximum grain of 5 mm.
The number indicates the average particle size and the concentration of the solution (1530 - d50 = 15 nm; concentration 30 %).
