Warum ist Wolframkarbid eines der am schwierigsten zu schmiedenden Materialien?
Ja Wolframkarbid does have a metallic binder (cobalt, nickel, etc.), but the volume of the binder is so small that it doesn’t support the flow and movement of the brittle Wolframkarbid filler during forging.
The problem is common in ceramics. Most ceramics can’t be forged for the same reasons as Wolframkarbid. Instead, you sinter them from a powder into their final shape, or to a “near net shape” condition and machine them to a desired finish and desired dimensions.
