摘要
PURPOSE: To inexpensively produce the fine wire having an excellent shape memory alloy characteristic by composing the melt of a TiNi-based alloy of specific atomic % of Ti and the balance Ni and substituting part of Ni with a specific element. ;CONSTITUTION: A cylindrical drum 1 is rotated by a revolving shaft 2. A cooling liquid layer 5 is formed by centrifugal force in this drum 1. A molten metal jet 9 of the TiNi-based alloy is injected from an injection nozzle 7 to the cooling liquid layer 5 and is solidified, by which the fine wire of the TiNi-based alloy is produced. The melt of the TiNi-based alloy is, thereupon, composed of the TiNi-based alloy which has a basic compsn. consisting of 49 to 51at.% Ti and the balance substantially Ni and is partly substd. in the Ni with ≥10at.% element having a thermal conductivity at 0°C of ≥100W/mk. As a result, the holes generated in the fine wires are suppressed.;COPYRIGHT: (C)1995,JPO
