Within the monograph, the writer summarises the implications got in study and investigations of the gas-liquid steel approach at temperatures regular of electrical arc welding and electrometallurgy methods. specified awareness is given to the issues of sorption of diatomic homonuclear gases, particularly nitrogen from electrical arc plasma, by way of steel melts. it really is proven that once the steel absorbs the fuel from plasma the method doesn't succeed in the thermodynamic equilibrium country. Investigations have been conducted into tactics happening within the gas-plasma layer bordering with the steel. those procedures confirm the gasoline content material of liquid metal.

Lakomsky was born in 1926 in Kramatorsk (Donbass region) in a family of a metallurgist. In 1950, he completed his education at the Zaporozh'e Engineering Institute in casting and in 1954 he finished his post-graduate the Academy of Sciences of Ukraine. This dissertation dealt with gases in cast iron; his scientific supervisor was Prof. V. Yavoiskii, the well-known expert on gases in metals. E. O. Paton Electric Welding Institute, National Academy of Sciences of the Ukraine, Kiev. At the Institute, Professor Lakomsky founded, developed and headed the scientific section concerned with the high-temperature interaction of liquid metals with gases in the plasma state.

Sieverts, it is known that the dissolution in liquid metal of diatomic homonuclear gases, such as nitrogen and hydrogen, is accompanied by gas dissociation and is described by the following equation The form of existence of the above mentioned gases in a metallic solution is atomic from the point of view of the first approximation. Hence, when solving them in a liquid metal, the molecular composition of the latter changes.

For non-hydride-generating metals, the greatest deviation from the theoretical value of has been observed in Ref. 52 J/(g·atom·K) was studied, the lowest one has been found in Ref. 13 J/(g·atom·K) for the liquid iron-hydrogen system. 21 J/(g·atom·K). 05 entropy units. 13 entropy units. 34 J/(g·atom·K), respectively. From these facts, it transpires that the experimental values of the standard partial entropy of hydrogen dissolved in liquid metals are quite close to the theoretical ones. Some erroneous experimental results can be found in Table 1.
