THERMAL FORMING OF REFRACTORY ALLOY SURGICAL NEEDLES

摘要

A method of thermal forming of refractory alloy suture needles is disclos ed. Needle blanks made from refractory alloys are used to form surgical need les, which are heated to a temperature above the ductile to brittle transiti on temperature but below the recrystallization temperature of the refractory alloy. The heated needle blanks are then mechanically formed into a surgica l needle.
