Why can’t non-ferrous metals be carburized?

You can carburize non-ferrous metals but it does not give similar results as you would expect in ferrous applications.

By increasing carbon content at the surface of a part, you can increase the likelihood of phases that are of higher strength (martensites in particular). Because many other metallic elements do not have a similar effect from carbon alloying carburizing would not be benificial.
