Controlling elastic modulus and ultrasonic property of Ti6Al4V alloy for ultrasonic scalpel

The near-β transus drawing was discovered to be a candidate process for obtaining the deformed bi-modal structure of Ti6Al4V alloys appropriate for ultrasonic scalpel in this study. This structure presents relatively high β phase content (39.5%) and {0001}<101̅0> α texture intensity, depicts low elastic modulus (92.4 GPa) and leads to a 77.2% increase in the alloy’s ultrasonic amplitude at a resonant frequency of 55 kHz. The alloy’s elastic modulus depicts a decisive effect on its ultrasonic properties that are closely related to phase content and texture type. This study gets insight into the mechanism of phase content and texture distribution affecting the elastic modulus and ultrasonic properties of Ti6Al4V alloy.
