초록
Vehicles, self-propelled guns, wheeled armored vehicles, etc. are manufactured by welding using homogeneous rolled armored steel (MIL-STD-12560) and high hardness armored steel (MIL-STD-46100). In order to verify the performance of the welded part, 'H'-shaped specimens are produced and then bulletproof tests are conducted, and the testing institutes are limited to some overseas testing institutes including the United States. In addition, it is an expensive test that requires at least 55,000 $/time including production cost. In addition, as only corporations in the United States can apply for and proceed with the bulletproof test, there is a problem that, in reality, domestic research institutes and corporations cannot test. In particular, when the low-temperature impact test, which is a general industry standard, is applied to evaluate the bulletproof performance of homogeneous rolled armored steel plates, the possibility of replacing the domestic H plate bulletproof test is expected to increase. Therefore, in this study, a basic study was conducted on the correlation between low-temperature impact toughness and hardness analysis results and bulletproof performance as a way to reduce cost/time and facilitate product supply and demand by replacing the existing H-plate bulletproof test.
