Notes:
New experimental methods for investigations of phase formation during SHS have beenestablished. First experiments using penetrating synchrotron radiation and energy dispersivedetectors 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 ImagingTechnique (TIT)) based on continuous registration of the whole combustion process by using highlysensitive IR-camera and software developed by MIKRON Instruments Co. (USA) was used forprecise registration of the combustion parameters. SHS was performed on different types of pureand doped complex inorganic materials in pellet and powder form in a range of dc magnetic fieldsup to 20 T and in electrical field strengths up to ±220 kV/m. The dc magnetic field was appliedduring the reaction, supplied either by a permanent magnet (transverse, up to 1.1 T) or by anelectromagnet (longitudinal, up to 20 T). The dc electrical field was applied along the direction ofthe combustion wave front propagation. The combined processes of SHS and SLS (Selective LaserSintering) of 3D articles for different powdered compositions were optimized with laser irradiationpower
