is close to 99% in Al-Zr alloy, a peritectic reaction of the alloy melt and Al3Zr to form Al solid solution occurs at 660.5 °C. The melting point of Al is only 0.5 °C lower than the peritectic reaction... strength of the Al wires with the largest extent is the generation of the Al3(Sc,Zr) phase. As the temperature of the alloy decreased, the solid solubility of Zr and Sc decreased, leading......

melting process parameters of electron beam cold hearth on the Al element evaporation in TC4 alloy was studied. The results show that when the raw material is the VAR ingot, the secondary ingot is got... components of TC4 alloy. When the raw material is the simple substance Al, the element evaporation loss increases in the melting stage, and it increases with the Al content increasing. Research......
