FIELD: process engineering.
SUBSTANCE: invention relates to suture needles, particularly, to forming said needles from refractory alloys. Needle blank is made from doped alloy. Note here that said blank comprises refractory alloy. At least, part of said needle blank is heated to temperature exceeding that of transition from plastic to brittle state but lower than alloy recrystallisation temperature. Needle blank is formed mechanically to produce suture needle. Suture needle formed from refractory allows more than single shape recovery without fracture.
EFFECT: longer life, higher strength and hardness.
