Modelling Safety System of Waveguides Made of Regenerated Hard Alloy

If obsolete munitions are no longer needed, then their components, in particular high-quality metals, are quite suitable for use. Hard alloys of the tungsten carbide-nickel-cobalt system have been developed with different content of components compared to the traditionally used tungsten-cobalt alloys, which, in the presence of the same binder percentage, have increased hardness and flexural strength and, due to this, increased wear resistance. It has been established that in the regenerated mixtures the cobalt content corresponds to its content in the original scrap, the content of bound carbon corresponds to the stoichiometric content for each grade of alloy, the content of free carbon does not exceed the norm, and the physical and mechanical properties of sintered alloys meet the requirements for standard alloys of the corresponding grades. To increase the flexural strength, it is necessary to choose a binder in the nickel to cobalt ratio of 0.5–0.6. The obtained WCNi alloy powders are not in high commercial demand, but they can be used to manufacture new designs of projectile cores. Compositions with new properties have been developed for mass use of the WC + Ni type powders for cutters of rock-cutting tools, mandrels, blanks, and dies for drawing wire and pipes from ferrous and non-ferrous metals.
