The paper provides an overview of modern methods for studying the dynamics structure formation materials. analysis possibilities dynamic electron microscopy and optical controlling structural-phase state materials in high-temperature fast-flowing processes is carried out. Methods pyrometry field SHS, gas-thermal spraying coatings, additive synthesis metal ceramic products are considered. A review a new non-contact method measuring temperature spectral degree blackness presented. results theoretical experimental studies aimed at implementing approach pyrometric control An example given complex structural formations: metal-oxygen, metal-carbon, on surface tungsten, molybdenum tantalum foil heated by electric current inert gas medium. It compares with microstructure microelement composition phases frozen samples. At end work, conclusion drawn rational organization observation from point view constructing automatic system.
