Abstract:

The latent heat of Al-Si alloy, prepared by vacuum arc furnace and with different Si content, was studied by differential scanning calorimeter (DSC). The results indicate that the latent heat of the primary phase and the eutectic phase should be computed independently, the latent heat of the alloy increased  with the mass fraction of Si increasing from 4.16％ to  21.4％, and the linear relationship of the latent heat of the hypoeutectic alloy and the hypereutectic alloy was  different, which were  Lhypo=353.4+12X and Lhyper=409.6+7.54X. It was also  found that it was  the different forms of Si in Al-Si melt and the pure Si melt that caused the different latent heat of the Si phase in different melt.

Key words:  Al-Si alloy, differential scanning calorimeter analysis, latent heat
