METHOD OF IMPROVEMENT OF MECHANICAL PROPERTIES OF PRODUCTS MADE OF METALS AND ALLOYS

摘要

The invention pertains to the domain of metallurgy in particular, thermochemical surface treatment of products made of metals, mainly steels, and their alloys and it can be used for products hardening for the purpose of their service durability increase.;The method of improvement of mechanical properties of products made of metals, mainly steels and alloys on their basis includes products nitriding in the gas atmosphere containing nitrogen and-or its compounds in the presence of a catalyst. Together the product and the catalyst are subject to hot isostatic pressing with observation of conditions of the barometric and temperature impact that provides achievement of dislocations density in the product's volume that satisfies conditions of transition of a part of the product substance into the positron state of the Dirac matter

1. The method of improvement of mechanical properties of products made of metals, mainly steels and alloys on their basis, includes product nitriding in a gas atmosphere containing nitrogen and-or its compounds in the presence of a catalyst, differing in that the product and the catalyst simultaneously expose to hot isostatic pressing with observation of conditions of the barometric and temperature impact that provides achievement of dislocations density in the product's volume which satisfies conditions of transition of a part of the product substance into the positron state of the Dirac matter.
