- Applications
VDM® Powder 738LC can be used for a wide range of processes:
- Laser based additive manufacturing
- Electron beam based additive manufacturing
- Coatings
- Direct energy deposition
- Overlay welding
- Cold and hot isostatic pressing (CIP / HIP)
VDM® Powder 738LC can be used for many demanding applications. Originally, it was developed and used for static and rotating components in aircraft turbines such as housings, mounting elements and turbine blades and vanes because of the excellent oxidation resistance.

- Microstructural Properties
VDM® Powder 738LC microstructure consists primarily out of a γ-phase matrix and the γ′ intermetallic phase of the form Ni3Al. The solid solution elements present are chromium, cobalt, tungsten and tantalum; these equally contribute to the structural stability of the alloy. Carbides and borides form the main grain boundary strengtheners.

Packaging & Availability
- Availability
According to the requirements of the powder based processes, VDM® Powder 738LC is available in a wide range of particle fractions from 15 to 250 μm. The typical powder atomization yield ranges from 0.1 to 300 μm. After atomization, the powder is sieved and air classified according to customers specifications. All production and handling operations are carried out under protective atmosphere (argon).

- Packaging
The whole production and packaging process at VDM Metals is under argon and the powder has no contact to atmos-phere. The standard powder is packed in plastic bags (5 kg/10 kg/20 kg) under argon inside of sealed plastic drums (6l).
Storage & Handling
- Handling
- Please note that powder transportation may result in segregation of particle sizes.
- Do not open the container in humid environment.
- After contact with air the powder has limited storability.
- Humidity can influence the powder properties.
