The effects, stipulated by polimorfic transformations in metal, may be important at this process. At present work the behavior of hydrogen was studied by calculation modelling. The computer program allowed to calculate in the real time regime and to use direct display of graphs. The results of computation confirmed a possibility of considerable concentration anomalies in hydrogen distribution, stipulated by essential differences of solubility and hydrogen diffusion coefficients in ? and ?-phases of weldment metal.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
