Mechanical Properties of Cu-Al-Mn-based Alloys and Their Application to Medical Guidewire

摘要：

The superelasticity (SE) of the Cu-Al-Mn-based alloys can be drastically improved by controlling the grain size, and the present alloys were hardened by ageing at around 250℃ - 400℃ which causes the bainitic transformation. Based on these results, a Cu-Al-Mn-based core wire for a medical guidewire with a superelastic tip portion and a high rigid body portion was manufactured. This new type of guidewire shows excellent pushability and torquability superior to those of stainless steel and Ti-Ni guidewires.
