Abstract：

The　fatigue　experiments　for　titanium　alloy　Ti60　under　different　uniaxial/multiaxial　thermo-mechanical　loading　modes　found　that　the　combined　action　of　high　temperature　and　tensile　stress　can　cause　the　debonding　of　the　second　phase　strengthening　particles　between　grain　boundary,　reducing　the　ability　to　resist　deformation　of　Ti60,　which　leads　to　a　decrease　in　the　fatigue　life　of　the　material.　In　addition,　mean　tensile　stress　increases　the　ability　of　cracks　to　break　through　intergranular　barriers　and　the　non-proportional　additional　hardening　caused　by　multiaxial　loading　exacerbates　the　formation　of　microcracks.　Both　will　increase　the　fatigue　damage　of　the　material.　The　fatigue　damage　mechanism　identified　in　this　investigation　can　reasonably　explain　the　fatigue　life　law　under　multiaxial　loading　at　high　temperature,　uniaxial　and　multiaxial　thermo-mechanical　fatigue　loadings.　©　2024　Elsevier　Ltd
