Study of Helium Diffusion to Grain Boundaries by the Method of Internal Friction

Source

For samples of iron and nickel the temperature of the grain boundary maximum of internal friction increases with the increase of concentration of helium in samples, and then it saturates, but the peak height decreases and then so saturates. A second type of dependence of peak height of internal friction on helium concentration for samples of austenitic steel of the 16-15 type has been found. Peak height increases, passes through a maximum, and then decreases to a constant value. Helium concentration in samples is calculated from internal friction data that corresponds to adsorption saturation of grain boundaries and binding energy of helium atoms with grain boundaries.
