Abstract The stress relief and ductile-brittle transformation of the metallic glasses Pd_(82.5)M_1Si_(16.5)prepared by spinning roll have been examined.It was found that theductile-brittle transformation temperature,T_B,and activation energy,△E_B,of theglasses composed by the preceding transition metals,e.g.,Hf,Ta,W,Re,are in-creased markedly and by the later ones,e.g.,Os,Pt,influenced slightly,but byIr,T_B is decreased too many.The mode of ductile-brittle transformation of themetallic glasses PdSi_(16.5)is different among themselves composed by the precedingand later transition metals.The comparison of the influences of additives on theirtemperatures and activation energies of the ductile-brittle transformation and glasstransition has been made.These behaviours have been discussed on the basis ofthe Gaskell′s model and the Engel-Brewer′s electron theory of transition metals.
