《Effects of trace Cr on as-cast microstructure and microstructural evolution of semi-solid isothermal heat treatment ZC61 magnesium alloy》
The composition of experimental alloys is shown in Table1.Alloys were prepared from high purity Mg,Zn and Cu ingots(99.9wt.%),and Cr particles(99.95wt.%);all metals were melted at a pit-type electric resistance furnace named SG2-7.5 kW under protective RJ-2 covering flux and Ar atmosphere.When Mg ingots were totally melted,Zn and Cu ingots preheated to 200°C were added to the magnesium liquid at 680°C.When the melting temperature rose to 760°C,Cr particles preheated to 200°C were added to the melt and kept for~30 min.Next,to refine and remove scum at 730°C,C2Cl6 refining agent with a weight ratio of 1:500 compared with the melt was added to the melt by mechanical stirring for2-3 min.Subsequently,at 710°C,after being held for 10-15 min,the melt was poured into a permanent mould made of steel preheated to 200°C.The specimens treated by SSIHT had the same size ofΦ15 mm×15 mm.
