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 (Δθrec), 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 Δθrec, trec and LPP.
