Abstract

The paper presents the results of the experimental research concerning modification of mechanical characteristics of resistance and plasticity in the process of drawing of 10TiNiCr180 stainless steel tubes with and without ultrasonic vibrations. The experiments were performed in the framework of the CEEX project (Excelence Research Program, Ministry of Education, Research and Innovation of Romania), Contract no. 293/2006. Modification of mechanical characteristics of resistance and plasticity is analyzed for the tube samples processed using the classical technology (CT) or ultrasonic vibration drawing (UVD) depending on the relative drawing velocity (vdr / vv).
