ABSTRACT:
Form-locking means and process for joining same to a sub-caliber projectile in a peripheral region thereof.
The form-locking means consist of a material in the form of an n-phase sinter alloy having a high content of at least one heavy metal, where n.gtoreq.2. The material forming the form-locking means in the peripheral region of the sub-caliber projectile form at least one further alloy phase. The form-locking means are joined to the periphery of the sub-caliber projectile in the form of a layer of predetermined thickness which can be joined to the projectile surface by recasting with a melt of the form-locking material or by flame-spraying such layer on the projectile surface.
