It can be seen that both TNand TGdecreasedwith increasing the Sr/Bi ratio. When one considers the char-acteristic parameters of thermal analysis for alloys with similarSr/Bi ratio, it can be observed that addition sequence has noeffect on the results of either structure or characteristic temper-atures. The results were more or less the same in terms of Sr/Biratio, at which the modification effect of Sr appears to have beenlost
