- Title
TRENDS IN MECHANICAL PROPERTIES ENHANCING OF STEELS USED FOR GUN BARRELS PRODUCTION.

- Abstract
The paper is focused on recent trends in mechanical properties enhancing of the steels used for sport or army guns barrels. Special conditions are required for these steels including high tensile strength Rm, surface hardness HV (HRC) as well as yield point Rp0.2 or impact value KV (KU). The strength could be improved by choosing some of new progressive materials as are Maraging, TRIP, TWIP or TMT steels. Some of these materials, their chemical composition, properties and strengthening methods are mentioned in the paper. Next part is focused on short description of howitzer or cannon barrel production and its heat treatment. Besides that, effect of electro slug remelting process (ESR) used as a method for barrels quality improving including experimental comparison of ESR treated and non-treated semiproducts is described in the paper.
