Thank you very much my friend.

hi i wold inquire you what the speed of cooling rate that i can get great eutictic for alsi7MG0.S MORPHOLOGY FIBREUS or branching morphology

At 2:20 you said '... two metals completely soluble in liquid state and completely insoluble in solid state.' Silicon is not a metal. You later said that 12.5% silicon alloys are preferred because it is the lowest melting temperature. That is not true. Wile 12.5% is the lowest melting temperature, (true), temperature plays almost no part in the selection of silicon content. First, 12.5% is not a very common silicon content in casting aluminums. Seven and nine percent is much more common in aluminum-silicon alloys. Maybe silicon content should be higher at 12.5% (it would reduce the shrinkage) but that is not the currently the case. Then in your example you use 319 alloy, which has only 6% silicon. And after your example you again say that "widely used alloys in the casting industry are the eutectic alloys particularly 12.5% silicon'" due to low melting point. Again, this is totally wrong. The small change in the melting point is not the factor in the percentage of silicon content.

Very good explanation

Hi i love your videos. I have a question. If I mix aluminum oxide and silica I think it will lower the melting point of aluminum oxide a bit. But what other elements or oxides can add to lower the melting point of aluminum oxide to the range of 1000 c? I know cryolite can do it but here I livbe is not available
