Abstract

We generalize the results of investigations performed at the Paton Institute of Electric Welding and aimed at elucidating the nature of the reversible hydrogen brittleness of structural steels. The state of the problem is analyzed, and a methodical approach is proposed for studying the problem at the atomic level. New ideas of the mechanism of reversible hydrogen brittleness are formulated, and their experimental substantiation is presented. It is shown that these ideas are useful for refining the methods of prevention of hydrogen embrittlement in steel structures while they are in production or in operation under conditions of hydrogen adsorption.
