Optimizing HIP and Printing Parameters for EBM Ti-6Al-4V

An investigation of HIP parameters for EBM Ti-6Al-4V has been performed with the aim to maximize the strength of the HIPed material. A lower HIP temperature of 800 °C and a higher pressure of 200 MPa gives the highest strength and is also enough to eliminate all internal defects. By printing materia...

Zusammenfassung:An investigation of HIP parameters for EBM Ti-6Al-4V has been performed with the aim to maximize the strength of the HIPed material. A lower HIP temperature of 800 °C and a higher pressure of 200 MPa gives the highest strength and is also enough to eliminate all internal defects. By printing material with intentionally induced porosity combined with an optimized HIP cycle the highest strength can be obtained.
