| Abstract: | The grain refinement of Mg-Al based alloys with carbon inoculation was investigated by a computer-aided cooling curve analysis(CA-CCA)system.The results show that carbon inoculation decreases the main parameters of the recalescence regime during the initial stage of solidification.These parameters include the recalescence undercooling(△θrec),duration of recalescence (trec),and liquid peak parameter(LPP)which is firstly introduced into magnesium alloys.The resultant grain size decreases with increasing nucleation temperature(θn)and decreasing values of △θrec,trec and LPE |
