抄録

A decrease in electrical resistivity of niobium-hydrogen alloys is observed during the isothermal aging at −196°C. It is shown that the aging process is a reaction with the time exponent of 1/3 and the activation energy of 0.10±0.02 eV . A change in flow stress is also observed with the aging at this temperature. These phenomena are not found in hydrogen-free niboium. It is suggested that the changes in resistivity and flow stress should be attributed to the hydride precipitation at −196°C.
