Abstract
The article contains biography of Tsolо Rashev – an outstanding metallurgical scientist of the 20th century. His life was devoted to the development of metallurgy in Bulgaria, to the research of metallurgical processes related to the production of nitrogen-containing and high-nitrogen steels and their various structural classes. Since his life was inseparable from this work, the article focuses on the main directions of his scientific activity. In particular, Professor Rashev has carried out the work on thermodynamics and kinetics of interaction of unconventional alloying elements with metals and slags in liquid and solid states, including studies on the solubility of nitrogen in melts of various iron-based alloying systems; on mathematical modeling of metallurgical processes; on technology and properties of high-quality, special and high-nitrogen steels and alloys. He has developed and implemented in practice methods and devices for processing and production of steels and alloys, paying particular attention to introduction and retention of nitrogen in steels and iron-based alloys. With his works Tsolo Rashev made an invaluable contribution to the world fund of scientific knowledge.
