Damage and fracture mechanisms in Ti-LCB and Ti-555 alloys : Micromechanical testing and modeling
Last modified: 2013-05-03
Abstract
New generations of β metastable and α/β titanium alloys are starting to replace the
classical TiA6V4 alloy in many aeronautic structural components. The damage
and fracture resistance of these alloys is not yet properly characterized and
understood, which limits the reliability of the structural integrity assessment
analysis as well as the optimization of the microstructures. Mechanical tests have
been performed under different loading conditions, from tensile tests on notched
and un-notched bars, on samples obtained with different thermomechanical routes
and involving different volume fraction, morphology, and distribution of the α
phase.
