Abstract (en)
[origin: WO9617698A1] A NiTi-based tube of memory metal is produced by extrusion, whereby: a) one starts off from a blank of a memory metal; b) a central hole is drilled in said blank; c) a core is introduced into the central hole, whereafter the blank is encased by a casing, and preferably also by two gables, whereby the blank is excluded from the surrounding atmosphere; d) the encased blank is heated and extruded; e) the ends of the extruded blank are removed; and f) also the core and the surrounding casing is removed. In this way, it has been accomplished to produce NiTi-based tubes of memory metal of hitherto unattained length, such as >/= 1/2 m.
