Microstructural optimization through heat treatment for enhancing the fracture toughness and fatigue crack growth resistance of selective laser melted Ti–6Al–4V alloy

Microstructural optimization through heat treatment for enhancing the fracture toughness and fatigue crack growth resistance of selective laser melted Ti–6Al–4V alloy

The yield strength (σᵧ) of Ti–6Al–4V alloy, additively manufactured via selective laser melting (SLM) of powder beds, can exceed 1000 MPa while possessing a mode I fracture toughness (Kιc) of ∼50 MPa√m. The possibility of enhancing Kιc as well as fatigue crack growth resistance, without a significan...
