| 中文摘要 | The diffusivity of hydrogen in two Nl(3)Al alloys has been measured in the temperature range 100degreesC to 420degreesC using an ultrahigh vacuum gaseous permeation technique. The diffusivity data fall into two segments, in which the hydrogen diffusivity adheres to the Arrhenius form, respectively. It is suggested that hydrogen transportation takes place along the grain boundaries at lower temperature and in the lattice at higher temperature. The intergranular fracture of L1(2)-type intermetallics induced by hydrogen at relatively low temperature results from hydrogen transportation along the grain boundaries, not in the lattice. |
