The specific heat of metallic glasses containing Si and B (Ni_Si_B_ and Pd_Si_) and Zr-based metallic glasses(Zr_Al_Cu_Ni_Co_, Zr_Al_Cu_ and Zr_Cu_) was measured in the temperature range 77-800 K using an a.c. calorimeter. Several exothermic and endothermic processes were observed correspondingly to the transformation sequences for complete crystallization of all the glasses. The structural relaxation process appears with a decrease in heat capacity. For Ni-Si-B and Pd-Si glasses an abrupt increase in the specific heat is observed at the glass transition temperature T_g. For Zr-based glasses, however, a monotonous increase in the specific heat is observed just below T_g. Then the specific heat makes a peak and decrease abruptly with increasing temperature. The height of the peak increases with heating rate
