The paper considers the use of hydrogen as a component of the technological process to solve an applied problem - the control of material defects, which consisted of controlled fragmentation of steel under dynamic loading to facilitate the cracking of the metal volume. Medium-carbon pearlite-ferrite steel of steel 60 types under electrochemical hydrogenation is studied. The criterion parameter of the material state was the energy of impact loading by three-point bending of smooth beam specimens. By selecting the electrochemical hydrogenation modes in terms of intensity (current) and duration of the process, as well as the composition of the electrolyte, a significant reduction in the energy intensity of steel fracture was obtained, which correlates with the residual hydrogen concentration in the metal. Metallographic analysis of the surface of the specimens confirmed the hydrogenation effect on the initiation of defects, which can be used for controlled steel fragmentation.

本文考虑使用氢作为工艺过程的一个组成部分来解决一个应用问题——材料缺陷的控制，其中包括在动态载荷下控制钢材的破碎，以促进金属体积的破裂。对60号钢中碳珠光体-铁素体钢进行电化学加氢研究。材料状态的判据参数是光滑梁试件三点弯曲冲击载荷的能量。通过根据过程强度（电流）和持续时间以及电解液的成分来选择电化学氢化模式，钢断裂的能量强度显着降低，这与钢中残余氢浓度相关。金属。样品表面的金相分析证实了氢化对缺陷萌生的影响，可用于控制钢的破碎。
