Meltio Titanium 64

Product catalog summary

Overview: The Meltio Material Datasheet Rev 3.0 provides detailed information on Meltio Titanium 64 (Ti-6AI-4V / ER Ti-5 / S Ti 6402c / 3.7165), a widely used alloy known for its high strength, low density, and corrosion resistance. It is primarily used in aerospace, marine, chemical, and automotive industries due to its excellent strength-to-weight ratio.

Material Properties: Ti64 is characterized by high strength, low weight, and corrosion resistance. The wire chemical composition includes elements such as Ti, Al, V, Fe, C, N, and H. The wire density is 4.4 g/cm³, with a melting point of 1947 K (1674 °C or 3045 °F).

Spool Specifications: The wire diameter is 1.0 mm, with a weight of 7.5 kg and a volume of 1704 cm³ on a BS300 spool type. The wire is uncoated to ensure compatibility with Meltio systems.

Heat Treatment: Heat treatment is recommended to enhance mechanical properties, making the alloy stronger, more ductile, and resistant to fatigue. The process involves heating in a vacuum atmosphere to 920°C, holding for 2 hours, and cooling to room temperature.

Deposition Parameters: For 3D printing, parameters include a laser power of 1100 W, velocity of 7.5 mm/s, argon flow of 20 l/min, layer height of 1.0 mm, wire speed of 9.6 mm/s, and energy density of 147 J/mm³.

Microstructure and Tomography: The microstructure consists of acicular martensite in the beta phase, with columnar grains due to epitaxial growth. Computed tomography scans show no detectable voids or defects, with a resolution of 24 µm per pixel and a relative density of 99.994%.

Mechanical Properties: The mechanical properties of 3D printed specimens are comparable to those made with conventional methods. After heat treatment, the ultimate tensile strength (UTS) is 802 MPa (XY) and 788 MPa (XZ), with yield strengths of 727 MPa (XY) and 693 MPa (XZ). Hardness values are 311 HV-30 (age hardened) and 303 HV-30 (as printed).

Fatigue and Oxidation: Fatigue studies show differences between age-hardened and hot isostatic pressed specimens due to residual porosity. Oxidation affects mechanical properties, with components showing 0.25% oxygen content and dispersed oxides like rutile and alumina.

Meltio Material Datasheet Tomography Computed Tomography Scan of 3D printed sample part in Ti64 without detectable voids or defects. Resolution of 24 pm per pixel. Meltio Titanium 64 Ti-6AI-4V / ER Ti-5 / S T1 6402c / 3.7165 Micrography The observed microstructure is composed of acicular martensite embedded in the beta phase. The columnar shape of the grains extends along the manufacturing direction due to epitaxial growth of the original beta phase. In the XY section, the microstructure appears as polyhedral grains of a' + (3, with alpha phases at grain boundaries. Relative density as 3D printed...

Meltio Material Datasheet Fatigue Meltio carried out a fatigue study on 3D printed specimens using two heat treatments, namely age hardening and hot isostatic pressing. The presence of residual porosity in the sample parts during the study, which has been resolved through process improvements, may explain the difference in fatigue behavior between the age-hardened and hot isostatic pressed specimens. Oxidation Oxidation is a crucial factor that particularly affects the properties and performance of 3D printed titanium samples. Titanium has a high affinity for oxygen when exposed to air at high...
