Investigation of the effect of ultrasound on deformability of gold alloys

Abstract

Effect of axial ultrasound vibrations on the technological parameters of the 14­carat gold wire drawing process is described. It is shown that ultrasonic wire drawing through two wire­drawing die leads to decrease of the drawing load up to 40% and number of cycles from six to ten and to increase of the single and total deformation level up to 45% and 70% respectively.
