A.S. Rogachev has developed a complex of advanced experimental methods and approaches that made it possible to reveal the main mechanisms of material structuring in the SHS wave (primary structuring) and thereafter (secondary structuring), which opens up new prospects for controlling structure formation of the materials fabricated by using combustion methods, which is considered to be hard to control.

A.S. Rogachev explored the mechanisms of structuring and high-temperature physico-chemical transformations in micro- and nano-heterogeneous systems (powder compositions, multilayer nanofilms, etc.), mechanical activation, and spark plasma sintering.

Based on the fundamental findings, A.S. Rogachev co-authored the design of new methods for producing various materials, including SiC, Ti3SiC2, TiB2-TiN — based ceramics; hard alloys TiC-Ni(Mo); titanium alloys with gradient porosity for biomedical applications; intermetallic compounds in the Ni-Al-Ti system; and pseudo-Cu/Cr type alloys with a complex hierarchical structure and prospective electrical and mechanical properties.

He also developed the methods for reactive sintering of refractory and dissimilar materials, such as graphite, carbon—carbon composites, heat-resistant nickel and titanium alloys, and engineering carbon steels.

Along with investigating materials, A.S. Rogachev is exploring the material-forming synthesis process. He was the first one to demonstrate the existence of the thermal heterogeneity of the gasless combustion front and its stochastic fluctuations nature at the microscopic level. The correlations between these parameters and the microstructure of the reactive medium were determined.

Based on these experimental findings, he developed the micro-heterogeneous model of gasless combustion. These findings may be used to develop new methods for the synthesis of nanocrystallic and amorphous materials in a gasless combustion wave. A.S. Rogachev has made a significant contribution to the experimental investigation of the so-called solution combustion synthesis, which allows for the fabrication of oxide and metal nanopowders with a narrow size and shape distribution (e.g., hollow microspheres) for subsequent spark plasma sintering of materials with unique properties. The self-sustained reaction in a cloud of reactive particles under vacuum and zero-gravity conditions was carried out for the first time in space and yielded highly porous refractory materials. The experiments were conducted at the Russian Space Station Mir and the International Space Station.

A.S. Rogachev and his employees are the founders for a new scientific field, i.e. the structural dynamics in micro- and nano-heterogeneous processes that play an important role in designing advanced engineering materials.

A.S. Rogachev’s strength is the ability to inspire researchers and to unite scientists from different organizations and countries by the work on the problem. He and his laboratory are actively collaborating with many research laboratories and universities both in Russia and abroad.

A.S. Rogachev has delivered numerous lectures and workshops at various academic organizations and has been repeatedly invited to speak at international conferences.
