Abstract:

Tensile and bend properties of nickel and iron-base amorphous alloys have been studied at 200 C in the presence of liquid lithium and in air. Nickel base alloys show severe embrittlement, except for Metglas 2826MB. The results are discussed on the basis of proposed mechanisms of LME and it is concluded that the embrittlement of amorphous alloys takes place by an enhanced shear mechanism. Hydrogen embrittlement also seems to occur by a similar process. Author
