概要 Rapidly solidified LaNi_5 alloy wires were prepared by the In-Rotating-Water Spinning Process. The spinnability and the effects of spinning conditions on the shape of prepared wire were examined using... a quartz nozzle of 0.5mm diameter. The drum rotational velocity was kept at 7.0m/s. The ejection pressure of melt ranged from 0.2 to 0.4MPa and the melt temperature from 1350 to 1520℃. About 30cm long straight wires with diameters ranging from 0.15 to 0.5mm were produced at a relatively high melt temperature of around 1500℃. However, the hydrogen absorbing capacity of the produced wires decreased by about 30% compared to ingot alloy. It was inferred that this was probably due to the reaction between the quartz nozzle and LaNi_5 during the melting process.続きを見る
