Popis:	Measurements have been made on cracking resistance in cast aluminum alloys by means of acoustic emission AE. Determining the crack start instant is important. Tests on prismatic and platey specimens made of Ti3Al and Ti5Al alloys have been made with three-point bending and stretching correspondingly. AE signals were recorded throughout the loading period up to failure. The stress intensity coefficient KIs at the start of cracking has been determined, as has that at failure Kc. Detailed relations have been established between KIs and Kc on the one hand and the AE signal parameters on the other. KIs is invariant with respect to specimen thickness. Data are given on the AE excitation mechanisms for titanium alloys on failure.
