Abstract

The paper investigates the influence of the hydrogen impurity in palladium on the migration of tilt grain boundaries with <111> and <100> misorientation axes. It is shown that the migration velocity of grain boundaries decreases with the increasing hydrogen concentration in palladium, and at 50% hydrogen concentration it is approximately twice as slow as in pure palladium. Moreover, during the transition from low- to high-angle grain boundaries, their migration mechanism does not qualitatively change. The ordered networks of atomic displacements are observed, with square (for <100> grain boundary) and hexagonal (for <111> grain boundary) networks which reduce in size with the increasing misorientation angle.
