Abstract: Effects of various processing parameters on quality of metallic wires fabricated by in-rotating liquid spinning method (INROLISP) were theoretically and experimentally studied.Al-Si alloy wires with uniform cross section and very fine grains could be fabricated stably under the conditions that the interior diameter of nozzle was 025-0.5mm,Ar pressure was about 0.4MPa,cooled liquid flowing rate was 400r/min,melt jet flying distance was 5-10mm,melt jet entrance angle was 35°-45° and the melt superheat degree was 100-150℃.In addition,the quality of the wires could only be assured under the conditions that special salts and active agents were added into the cooling liquid to improve its cooling capacity and decrease its surface tension.
