The effect of heat treatment parameters on the structure and fatigue cracks growth in steel–titanium bimetal

The paper describes the influence of annealing temperature on the change in the structure and cracks growth and fatigue life in the bimetal titanium–carbon steel obtained by explosive welding (cladding). Cyclic bending test was performed for different levels of annealing temperature on specimens of the bimetal having a rectangular cross-section and a fatigue crack growth was measured by microscopy. Structure changes of carbon steel, titanium and explosively welded area induced a different hardness distribution. It discloses the relationship between the level of the annealing temperature, the propagation of fatigue cracks, changes in the structure and hardness level.
