The penetration depths of hydrides formed in 6.8 kbar of gaseous hydrogen in cylindrical samples was investigated at 25°C in Pd-Ni alloys of 80, 120, 150, 200 and 250 mi mdiameters. The exposition time was about 4 months, thus, sufficient for the stationarity in respect to equilibration of the sample composition. In all alloys the penetration depth was limited, exhibiting a linear increase with radii of the wires applied with the slope of about 0.6 mi m per 1 mi m of the wire radius. These results are interpreted in terms of the coherent character of the hydride formation, supporting the thermodynamic reason for the limited penetration depth of metallic hydrides.
