The paper contains results of investigations of the crack growth in plane specimens made of Ti-6Al-4V titanium alloy and AlCu4Mg1 aluminium alloy under cyclic bending. The tests were done on specimens with the stress concentrators being one-sided sharp notch. On the fractures there have been observed first of all transcrystalline cracks through the α phase grains for both materials.

Initiation And Propagation

The paper contains the results of experimental work carried out in order to analyse the initiation and propagation of fatigue cracks in S355 steel. The tests were performed on plane specimens with the stress concentrators in form of the external two-sided blunt notches. Tests were performed on specimens with fillet welds (concave and convex) made of S355 steel, subjected to cyclic bending.

The paper contains the results of experimental work carried out in order to analyse the initiation and propagation of fatigue cracks in Ti-6Al-4V titanium alloy. The tests were performed on plane specimens with the stress concentrators in form of one-sided sharp notches. The tested specimens were made of the oxygenated Ti-6Al-4V subjected to various variants of heat treatment.

Cracks Propagation

In this paper the results of experimental tests of the fatigue cracks propagation in Ti-6Al-4V titanium alloy subjected to cyclic bending are presented. The tests were performed on plane specimens with the stress concentrators in form of one-sided sharp notches. The tested specimens were made of the Ti-6Al-4V alloy subjected to oxygenating, and hardening and ageing. In the specimens after heat treatment, crack in the core has quite a different course than in the hardened oxygenated top layers.
