Two kinds of Zr-based amorphous powders were mixed with LiF + MgF2 flux powders, and were deposited on a pure titanium substrate, on which electron beam was irradiated to fabricate one-layered surface composites.
The mixture of VC powders MgO CaO flux powders was deposited on a plain carbon steel substrate, and then electron beam was irradiated to fabricate a surface composite layer of 1.8 mm in thickness.
For example, the D20 diffractometer at ILL Grenoble, the world's highest flux neutron powder machine, can collect complete patterns at 100 ms intervals, and this has been important for the real time study of explosive SHS reactions.
System design, the fundamental features and challenges of fluidization stability such as mass flux uniformity, powder transport and heat transfer, as well as auxiliary power minimization are thoroughly discussed.
In the presented work under the influence of neutrons with 2×1013 n/cm2 s intensity it has been studied the dependence of activities of radioactive nucleus, formed in the result of neutron flux in powder and extruded shaped, 99,5% purity, 20 nm size nano SiO2 compound, on integral dose and decomposition time after irradiation.
The value of neutron flux for powdered samples is 3,95×1018 ÷ 1,58×1019 and for tablet-formed ones it changes within the neutron range 6,67×1017 ÷ 2,67×1018.
The powder flux model validation results showed coherence between the estimated and measured particle flux values, particularly when the powder stream presents a Gaussian profile.
In this research work a numerical model which simulates the powder flux distribution on a coaxial nozzle is presented.
A new control system for regulating the powder flux during the laser metal deposition process (LMD) has been designed, developed and validated.
Radially non-uniform distributions of powder flux, solid holdup and particle velocity were determined by powder sampling and photographic observation of the tube.
