On a special stand, samples prepared from 27MnCrB5-2 steel were tested. The steel samples were heated to 950°C and then cooled continuously in the air. Signals from phase changes occurring during cooling were recorded using the system for registering acoustic emission. As a result of the changes, Widmanstätten ferrite and bainite structures were observed under a scanning microscope. The recorded acoustic emission signal was analyzed and assigned to the appropriate phase transformation with the use of artificial neural networks.}, type={Article}, title={Application of acoustic emission to the analysis of phase transformations in 27MnCrB5-2 steel tests during continuous cooling}, URL={http://www.journals.pan.pl/Content/121314/PDF-MASTER/Z_27_02233_Bpast.No.69(6)_OK.pdf}, doi={10.24425/bpasts.2021.139389}, keywords={microstructure, phase transformation, ultrasonics, acoustic emission, continuous cooling}, }
