| 摘 要： | The modification effect of a new type of Al-P master alloy on Al-24Si alloys was investigated.It is found that excellent modification effect can be obtained by the addition of this new type of Al-P master alloy into Al-24Si melt and the average primary Si grain size is decreased below 47μm from original 225μm.It is also found that the TiC particles in the melt coming from A18Ti2C can improve the modification ffect of the Al-P master alloy.When the content of TiC particles in the Al-24Si melt is 0.03%.the improvement reaches the maximum and keeps steady with increasing content of TiC particles.Modification effect occurs at 50 min after addition of the Al-P master alloy and TiC particles,and keeps stable with prolonging holding time.

| Abstract: | The modification effect of a new type of Al-P master alloy on Al-24Si alloys was investigated. It is foundthat excellent modification effect can be obtained by the addition of this new type of A1-P master alloy into Al-24Simelt and the average primary Si grain size is decreased below 47 μm from original 225 μm. It is also found that theTiC particles in the melt coming from Al8Ti2C can improve the modification effect of the Al-P master alloy. Whenthe content of TiC particles in the Al-24Si melt is 0.03 %, the improvement reaches the maximum and keeps steadywith increasing content of TiC particles. Modification effect occurs at 50 min after the addition of the Al-P master al-loy and TiC particles, and keeps stable with prolonging holding time. |
