(Peter the Great Saint-Petersburg Polytechnic University) The researchers from Peter the Great St.Petersburg Polytechnic University and Institute of Problems of Mechanical Engineering of the Russian Academy of Sciences studied the distribution of hydrogen in metals in the process of standard testing for hydrogen cracking. They found that there is a surface effect that does not let hydrogen enter the metal. This can result in errors in industrial quality control of material, and to fundamental errors in terms of scientific research of hydrogen embrittlement.
