| Abstract |
New experimental methods for investigations of phase formation during SHS have been
established. First experiments using penetrating synchrotron radiation and energy dispersive
detectors for different classes of complex inorganic materials were carried out at ESRF (Grenoble,
France) and Daresbury (UK). A new and very sensitive thermal imaging method (Thermal Imaging
Technique (TIT)) based on continuous registration of the whole combustion process by using highly
sensitive IR-camera and software developed by MIKRON Instruments Co. (USA) was used for
precise registration of the combustion parameters. SHS was performed on different types of pure
and doped complex inorganic materials in pellet and powder form in a range of dc magnetic fields
up to 20 T and in electrical field strengths up to ±220 kV/m. The dc magnetic field was applied
during the reaction, supplied either by a permanent magnet (transverse, up to 1.1 T) or by an
electromagnet (longitudinal, up to 20 T). The dc electrical field was applied along the direction of
the combustion wave front propagation. The combined processes of SHS and SLS (Selective Laser
Sintering) of 3D articles for different powdered compositions were optimized with laser irradiation
power. |
