    Abstract

    This paper investigates an application of ultrasonic stirring in water and oil-immersion quenching of a medium carbon steel sample. By developing a pressure acoustic simulation, the distribution of ultrasound pressure and acceleration in quenching media was predicted. By using the standard temperature probe of Inconel 600, the cooling curves of water and quench oil were recorded with and without ultrasound agitation. Using the same conditions, a quenching of the steel cylinders made for carbon steel C45 was performed. The experimental results have shown a significant impact of ultrasound agitation on cooling curve parameters, sample distortions, and surface hardness distribution and its hardenability.
