When producing ultrasound surgical instruments functionally gradient materials are used. They provide transmission and mechanical reinforcement of high intensity longitudinal ultrasonic waves. The sound velocity variations in the material along the axis of the ultrasound instrument may occur when using the thermal processing such as annealing and hardening. The work contains literature review regarding the impact of various heat treatment types on the sound velocity in alloys and analyzes the influence of the sound velocity change in ultrasound instrument’s part on its amplification gain. We select titanium alloy VT-6 as the material for producing the ultrasound instrument.
