摘要
In order to remove hydrogen and inclusions from A356 alloy melt, a low melting point glass flux, JDN Ⅱ, was developed. The results indicated that JDN Ⅱ flux has distinct effect of purification and protection on A356 alloy melt. When the dosage of the flux was 3%, the content of hydrogen in A356 melt was only 2.6?mL/kg at 857?℃ and 0.7?mL/kg even at 750?℃. In the meantime, the mechanical properties of the alloy increase greatly with the covering of 3% JDN Ⅱ flux. Compared with no flux, the tensile strength of A356 alloy increases by 9.42% and the elongation increases by 22%. The purification mechanism of JDN Ⅱ glass flux was discussed too.
