| Abstract: | The heat capacities (C_p) ofglassy and crystalline Fe_(40)Ni_(40)B_(20) alloy have been measured by means ofdifferential scanning calorimeter(DSC). A larger C_p value at the glass transition temperature (T_g) can be obtained. The reproducible C_p values ofrelaxed glass at certain heating rate are lower than that ofas quenched glass below 500 K, and are much higher at T_g than that of the crystal. The heating rate affects C_p values of the glass. At last, C_p val ues ofthe undercooled liquid are estimated. |
