PROCEDURE FOR THERMO-MECHANIC TREATMENT OF SHEET ARMOUR STEEL

摘要

FIELD: metallurgy. ^ SUBSTANCE: steel sheet is rolled at temperature below temperature of re-crystallisation of austenite, but over temperature of ferrite transformation of steel and cooled directly upon rolling from temperature not below temperature of ferrite transformation of steel. ^ EFFECT: optimisation of procedure of sheet armour steel hot rolling facilitating increase of ballistic resistance due to suppression of undesirable crystallographic texture. ^ 2 cl
