Improving Ballistic Resistance of Armor Steel by FCAW with Hardfacing Alloys of Fe–Mo–Mn–B–C System

Management Systems in Production Engineering
Armor steels can be strengthened against modern ballistic threats through surface hardfacing with advanced Fe-based alloys. This study develops a series of flux-cored arc welded (FCAW) hardfacing alloys in the Fe–Mo–Mn–B–C system to enhance the ballistic
