Abstract
Future developments of the In-Rotating-Liquid Spinning Process (INROLISP) was discussed with reviewing past results. Following countermeasures will be necessary to come into wide use but their order of priority shifts according to each purpose: 1) using a melting process to prevent melt from contamination (ex. the cold crucible melting), 2) improving the inner surface in the nozzle (ex. metal-oxide liner on metalbase), 3) controlling the oxide skin on the jet, 4) lowering density and adjusting the cooling ability in the coolant, 5) analyzing and controlling for solidification morphology under the boundary-layer separation between jet and coolant, 6) raising the observation technique of the jet, 7) speedy taking as-spun wires out of the drum. The INROLISP should not be expected to become all-round process but should be variously modified to be suitable for each purpose. As an example the spinning in gas process, which can make unidirectional solidification, was proposed. In the course of developing, it is important not to lose what merit is expected in the spinning process.
