《Mechanisms of reactive element Y on the purification of K4169 superalloy during vacuum induction melting》
wt%
The nominal composition of K4169 superalloy is shown in Table 1.Different contents of rare earth element Y(0,0.005wt%,and 0.1wt%)were added to the alloy.The alloy ingots were obtained by VIM in a 100-k W ZG125C VIM furnace.Before melting,the chamber was evacuated to the vacuum pressure of 3.5×10-3 Pa and backfilled with pure argon(O2<10 ppm;N2<50 ppm;H2<5 ppm;and CH4<4 ppm)up to 0.05 MPa for three times to reduce the O content to a minimum level and avoid the evaporation of alloy components.The superheating temperatures used were 1550,1600,and 1700°C.The refining time was set as 10 min,and the pouring temperature was 1480°C(measured and controlled by an IR thermometer).The Y2O3 ceramic crucibles with a purity of 99%were prepared by cold isostatic pressing at 180 MPa and sintered in a vacuum resistance furnace at 2000°C.
