MANUFACTURING METHOD OF SANDWICH PLATE BASED ON ALUMINIUM FOR BULLET-PROOF WELDED ARMOUR

摘要

FIELD: weapons and ammunition.;SUBSTANCE: method consists in obtaining the workpiece to be rolled and its heating, hot rolling of plate according to the size requirements, cooling down to room temperature and artificial ageing. Production of workpieces to be rolled involves rolling according to the size requirements of ingots and/or slabs from aluminium alloys for sandwich plate and assembly of a pack using them. Pack is heated at 500-550°C during 5-7 hours. Rolling according to the size requirements is performed at 410-450°C. Additional hardening is performed at 450-480°C. Artificial ageing is performed at temperature of 110-120°C during 24-36 hours.;EFFECT: improving armour properties and durability of sandwich plate.;5 cl, 1 tbl
