Thesis topic: Performance speeds martensitic transformation when shooting power acoustic pulses deals with the thermal processing of steel when recording acoustic emission. The theoretical part deals with the hot gas transition, martensitic transformation, refining steel, and basic information about the acoustic emission. The practical part consisted of sensing acoustic emission during hardening steels in water and in oil, followed by detecting the hardness in different locations of the sample. Evaluation was carried out using a hardness test, metallographic images and records acoustic emission obtained during hardening.
