German designs have a helical rib on the penetrator which prevents it from buckling or snapping too easily

 

Not entirely sure whether this is a German design (seeing the Asian text), but it does show the helical rib:

The characters are of the Hangul alphabet i.e. Korean. This here looks like a K-276 APFSDS-T, made out of specially-treated tungsten to allow less deformation upon penetration.

Well, "treatment" might not have been the correct term. More like "forging process".

From what I hear it's some sort of multi-stage heating process that helps reinforce the long rod's tungsten and diminish deformation during the self-sharpening phase. The same trick was apparently applied to the K-279. And that's about all I know on the matter. :-/

I had vaguely heard of this sort of thing being researched.  The idea was to alloy/treat tungsten in such a way that it behaves more like uranium on impact.
