Charpy impact testing of a high strength low-alloyed (HSLA) steel has been performed by simultaneously recording two independent signals. The magnetic emission (ME) and potential drop (PD) techniques were used to determine critical crack initiation properties on standard V-notched and pre-cracked three-point bending specimens at room temperature. Both signals (ME and PD) were recorded and compared, with the purpose of more precise identification of critical fracture mechanics parameters determining the onset of ductile crack growth. Standard Charpy specimens made of HSLA steel, oriented perpendicular to rolling direction were tested by a modified instrumentation of the Charpy machine, which included the original magnetic emission, and the potential drop techniques. The strain gauges and emission probes, located on the hammer tup, measured the force, thus both the magnetic and electric potential drop signals were monitored and recorded as a function of time. The obtained results indicat...e good agreement between ME and PD techniques on evaluation of ductile crack growth initiation point.
