Abstract In recent years,(0001) twist grain boundaries (BTGBs) located in primary α grain
clusters were identified as fatigue crack nucleation sites in different Ti alloys. In the present …

Heat treatment is critical for enhancing the mechanical properties of high strength titanium
alloys, especially for exploiting the potential of laser additive manufactured titanium alloys. In …

The deformation mechanism and life prediction model of titanium alloy laser-arc hybrid
welded joint during fatigue were studied. At the relatively small maximum cyclic stresses σ …

TA15 titanium alloy components produced via wire-arc direct energy deposition (WA-DED)
face challenges related to grain coarsening, suboptimal mechanical properties, and …

Wire and arc additive manufacturing (WAAM) enables rapid near-net-shape fabrications of
large-size parts and in-situ remanufacturing in many industry sectors. A comprehensive …

Multilayered structures of dissimilar titanium alloys can achieve excellent fracture ductility
and strength, while their fatigue characteristics especially dislocation networks and twin …

This study investigates the mechanisms through which water jet (WJ) enhancement affects
surface integrity and crack propagation in Ti/Al composite plates. Finite element models for …

In this study, an Enhanced Hosford–Coulomb (EHC) fracture model is proposed, which suits
a wide range of stress states. The model is validated by quantitatively investigating the …

Ultrahigh-strength titanium alloy (≥ 1250 MPa) innovation calls for an integrated framework
combining novel deformation processing and microstructural control. However, a confluence …

This paper aims to investigate the correlation of fatigue damage mechanisms with acoustic
emissions in a titanium alloy having multiple main microtextures. In the study, electron …
