Overview

This analysis reveals the mechanical properties and microstructure characteristics of Ti-17 processed by wire arc directed energy deposition, indicating key factors impacting performance.

Key Points

  • Processed Ti-17 shows improved strength exceeding 1100 MPa, while exhibiting low ductility.
  • Microstructural banding in as-built states contributes to variations in hardness, reaching up to 133 HV1.
  • Continuous α phase film at the grain boundaries is identified as a primary cause for reduced ductility.
  • Anisotropy in tensile properties is linked to loading direction and prior β grain boundaries.
