As shown in Fig. 7, the effect of wall material proportion on
powder yield at 30 and 40% TS was completely disparate. In the 30% TS, powder yield was increased with higher GA and MD and lower
GE from reference blend. Also, powder yield was rapidly decreased
with higher GE and lower MD from reference blend. It could be said
that GA decreases from reference blend had not effect on powder
yield.
In the case of 40% TS, powder yield increased with variation of
MD and GE from reference blend. In contrast toMD and GE, powder
yield decreased with variation of GA from reference blend. In both
30 and 40% TS, GE level had the greatest influence on the powder
yield than MD and GA.
