STEEL GRAIN-ORIENTED ARMOUR

摘要

FIELD: weapons and ammunition. ^ SUBSTANCE: steel armour is proposed. Armour consists of combined armoured plate made in the form of monoblock, containing front layer, intermediate layer and rear layer. Front layer is made from high-strength steel with hardness of 58Ç64 HRC; intermediate layer is made from grain-oriented steel with grain orientation {111} in the sheet plane, and rear layer is made from armoured steel with hardness of 52Ç56 HRC and thickness of 0.5Ç1.5 of thickness of front layer. ^ EFFECT: increasing armour stability level.
