This paper presents the results on the effect of alloy composition on the amorphous phase formation, crystallization temperature (Tx), hardness (Hv) and thermal embrittlement of (X, Y)_<76>Mo_8C_<16> and (X, Y)_<64>Mo_<20>C_<16> (X, Y=Fe, Co and Ni) quaternary alloy systems. Continuous amorphous ribbons possessing good ductility were obtained in the limited ragne of 0-46 at. %Co for (Fe, Co)_<76>Mo_8C_<16>, 0-31 at. %Ni for (Fe, Ni)_<76>Mo_8C_<16> and in the entire composition ranges of (Fe, Co)_<64>- and (Co, Ni)_<64>Mo_<20>C_<16> Hardness decreased by the replacement of Fe with Co or Ni, and of Co with Ni, exhibiting a minimum value at about 0.7 Co/Fe+Co, 0.6 Ni/Fe+Ni and 0.7 Ni/Co+Ni. Further replacement resulted in an increase of the hardness. Crystallization temperature decreased by the replacement of Fe with Co or Ni over entire composition ranges and in the Co-Ni system it was almost constant. The embrittlement tendency increased by the replacement of Co or Ni with Fe and by mixing Co and Ni.
