Conclusions Based on the results of tests, the following conclusions can be drawn: a) generation of an initial crack in CT specimens for heterogeneous materials including the analyzed multi-layer material Al/Ti, by means of cyclically variable loadings, does nor ensure obtainment of its proper form , b) an analysis of the cracking process during generation of a fatigue crack showed different precrack length for AA2519 aluminum alloy and Ti6Al4V titanium alloy - the differences do not exceed 5 %, c) tests results have confirmed that the explosion welded layered material Al/Ti meets the criteria for application of a linear elastic crack mechanics to be used for a description of its fracture toughness, d) decreasing the temperature slightly affects crack resistance of layered material Al/Ti and the one described by K Q parameter determined according to ASTM E 399 – norm, the differences do not exceed 11%, e) a comparison of crack resistance of a layered material and component materials under cryogenic conditions show that a layered material is characterized by crack resistance similar crack resistance of an aluminum alloy and significantly lower than a titanium alloy.
