Abstract:

The fatigue crack initiation and propagation in plain and notched specimens of titanium IMI 550 alloy with different percentages of transformed β-phase has been investigated. The S/N curves for plain specimens having a two-phase α/β microstructure were superior to those having a 100% transformed β microstructure. It is thought that this difference is due to easier crack paths in the β-stabilized samples, which contain very large grains. The notched S/N curves, however, were not dependent on microstructure. The overall crack propagation rates were similar for the three microstructures studied. © 1985.
