Hot Isostatic Pressing for Laser Powder Bed Fusion Ti64
Free Whitepaper
Hot Isostatic Pressing (HIP) is a manufacturing and post-treatment method commonly used for densification of powders and solid parts. Heat treatment can be combined with HIPping. HIP post-treatment is also commonly used as a risk mitigation measure for aerospace and medical components manufactured with Laser Powder Bed Fusion.

Additive Manufacturing (AM) of titanium Ti-6Al-4V (Ti64) by Laser
Powder Bed Fusion (LPBF) results in a metastable microstructure
that differs significantly from that of conventionally manufactured titanium. The high cooling rates in laser melting allow the formation of very fine martensitic microstructure.
Because of this different as-built microstructure, it seems likely that the conventional post treatments, including Hot Isostatic Pressing (HIP), could be optimized for improved part properties.
The aim of the study was to investigate possibilities to adapt
current standard titanium alloy HIP treatment (920 °C, 100 MPa, 2 h) to better fit LPBF Ti64.
This whitepaper gives answers to:
- What is the metallurgical background of HIP parameter optimization?
- How do different HIP parameters affect the material properties?
- What are the optimized HIP parameters for LPBF Ti64?
