ISS Science for Everyone

Science Objectives for Everyone
The Self-Propagating High Temperature Synthesis in Space - 1 (SVS-1) suite of investigations establish a mechanism for combustion and structural formation in self-propagating, high-temperature synthesis systems under conditions of weightlessness. SVS consists of 6 distinct investigations. Study the effect of weightlessness on the mechanism of combustion and structural formation in self-propagating, high-temperature synthesis systems (powder mixtures and compressed samples).

Applications

Space Applications
Establishing the mechanism of combustion and structural formation in self-propagating, high-temperature synthesis systems in weightlessness will make it possible to obtain high-melting materials with unique foam structures or granular frameworks, which are efficient heat insulating materials for use in space technology. Investigating the materials obtained through self-propagating, high-temperature synthesis in long-term microgravity demonstrated the potential for obtaining highly porous foam materials and coatings for use in the aerospace industry in weightlessness.

Earth Applications
The Earth Application for this investigation has yet to be identified.

Results/More Information

In the framework of the experiments conducted, the mechanisms of combustion and structural formation in self-propagating, high-temperature synthesis systems in microgravity were established, and methods of synthesizing highly porous, high-melting, heat-insulating materials with unique properties were developed. Materials with granular structures and foam materials based on self-propagating, high-temperature synthesis systems were obtained, and experiments were conducted to obtain coatings and connections via self-propagating high-temperature synthesis, SHS welding, and SHS soldering in space conditions.

The results of the studies [SVS-1] and [SVS-2] showed the high gravitational sensitivity of the processes taking place in the combustion waves and high temperature transformation liquid phase products. Unique macro and microstructures of cast combustion products and porous materials were obtained in microgravity. The interaction of the metal and oxide phases that formed during synthesis was investigated.
