Abstract:

Liquid metal embrittlement of four iron-base amorphous alloys has been demonstrated by means of tensile and bend tests. Fractographic features are shown to change markedly when fracture is accomplished under liquid metals. Similarities are noted between fractographic features in liquid metals and after hydrogen charging. The results are shown to be generally consistent with a model of adsorption-enhanced shear at crack tips by embrittling agents. Author
