The article presents the results of an analysis of the crack growth and fatigue life of CT specimens made of explosively welded AA2519–AA1050–Ti6Al4V layered material for the construction of air and space structures. The investigations were carried out for two temperature conditions: ambient temperature (293 K) and under cryogenic conditions at the temperature of liquid nitrogen (77 K). The analysis of the test results revealed the impact of cryogenic conditions on the process of fatigue cracking of a layered material. However, this impact is partly limited by a significant scatter of the test results, which may be caused by the different character of the process of cracking.
