The topic of this paper is an analysis of ultrasonic internal dumping of low carbon steel in dependence on temperature. The damping measurements were performed in range from 20 to 350 C measured data are presented in the form of dependence of internal damping on temperature. Two internal damping maximums were measured at the temperature of 170 and 210 C. The precipitation process running in material from about 200 C was measured. This leads to increated hardening and Young's modulus.
