Method & Evidence

AimTo investigate the mechanical properties, specifically tensile behavior and fracture toughness, of hybrid Ti6Al4V structures created by combining additive manufacturing with subtractive milling, and to assess the quality of the interface between the two material types.

MethodExperimental investigation and material characterization.

ProcedureHybrid Ti6Al4V pre-forms were created by additively manufacturing material onto a wrought Ti6Al4V start-plate, followed by milling to extract specimens. Uniaxial tension and compact tension specimens were then tested to evaluate tensile properties and fracture toughness. Microstructural analysis was performed to examine the interface between the additively manufactured and wrought materials.
