A letter of farewell to Giorgi Oniashvili

It is with great sadness that LEPL Ferdinand Tavadze Metallurgy and Materials Science Institute informs you that our dearest worker, famous scientist and honorable citizen, head of the Materials Science of Institute, Laureate of the Georgian National Award and Giorgi Nikoladze Prize, Doctor of Technical Sciences, Professor Giorgi Oniashvili passed away at the age of 78 due to a short-term, serious illness.

Giorgi Oniashvili spent his childhood and adolescence in Batumi, where he graduated with honors and in 1959 enrolled at the faculty of Metallurgy of the Georgian Polytechnic Institute. After graduating from the institute, he completed his compulsory military service and in 1968, he started working at the Institute of Metallurgy of the Georgian National Academy of Science, which was already highly prestigious by that time. He worked there until the end of his life.

Here he defended his PhD and doctoral dissertations, here he became a researcher of the highest rank, here he headed the High-Temperature Synthesis problematic Laboratory, and in the last years, he was fully in charge of Materials Science Department of the Institute. And, most importantly, Mr. Giorgi conducted all these works with great love, passion and success. To prove this, we can name about 130 scientific works performed by him at the highest level, most of which have been published in highly rated journals, have been reported in prestigious international scientific forums and have been awarded the Georgian National Award (2010) and Giorgi Nikoladze Prize (2014).

Giorgi Oniashvili's contribution to the introduction and dissemination of Self-Propagating, High Temperature Synthesis (SHS) in Georgia is remarkable. To make this seemingly obscure name understandable to the public, we will make a small retrospective review and a proper explanation.

The scientific concept of Self-Propagating High-Temperature Synthesis is based on the phenomenon discovered during the study of solid rocket fuel – solid-flame combustion, which became known to a wide range of scientists in 1978. This discovery immediately attracted the attention of our institute and its followers, as it became clear that the SHS method could solve many, previously unresolved questions of materials science. Among the first enthusiasts was Giorgi Oniashvili, who was the first to embrace this idea and served it with his usual devotion throughout his life. He made a name for the Georgian School of Materials Science and repeatedly praised his scientific achievements at the international conferences, including the SHS Symposium, which has been held 15 times in Europe, Asia, the USA and in 2017 in Georgia. It should be noted that Mr. Giorgi Oniashvili was a constant member of the International Committee of the SHS since 2004 and he was one of the recognized leaders in this field in the world.

Under the leadership of Giorgi Oniashvili, Institute designed and built a special original equipment and installations for carrying out the SHS process in a variety of conditions, synthesized a completely new sintered-hard alloys. It was the first time when we obtained manganese enriched ligatures from industrial waste from the manganese (manganese dust, slimes and other). Special monograph was devoted about the above-mentioned facts led by Giorgi Oniashvili, which was printed in English in Germany, 2018. Under his guidance, the institute has adopted single-phase compounds with unique properties of intermetallics, including in the nanostructural state. It is worth noting that it is impossible to obtain such products with existing technologies. In 2010, a group of employees of the Institute under the leadership of Giorgi Oniashvili was awarded the Georgian National Award for these works, and in 2013 for the cycle of works "Synthesis of single-phase nanostructured materials in the titanium-aluminum system" - Giorgi Nikoladze Prize.

Finally, in a few words, we will focus on the importance of materials science. The material used by man in the process of practical activity has determined the history of mankind, we say: the Stone Age, the Bronze Age, the Iron Age, and thus unambiguously define the specific stage of civilization. Material, as the basis of human activity, still has a global significance today. It is no coincidence that the modern civilized world considers the issues of material science along with biomedicine and ecological problems to be the priority of the 21st century.

By losing Giorgi Oniashvili, our society has lost a distinguished scientist and honorable citizen, his family - a wise leader, a loving father and grandfather, and we - a loyal friend, head of feasts and excellent companion.

The COVID-19 pandemic greatly complicated the relationship with Mr. Giorgi. His friends, with whom he spent most of his conscious life, found themselves stranded in the face of a bitter reality due to well-known restrictions.

The institute says goodbye to Mr. Giorgi Oniashvili and expresses its sorrow over the fact that due to the situation created by COVID-19 in the country, such a worthy member of our society could not be properly mourned.
