【Abstract】 Fracture analysis of 5B05 (LF10) antirust aluminium preformed armor rods were studied by metallography and SEM.The results show that the fracture of the antirust aluminium preformed armor rods result from theirs improper annealling as well as the metallic inclusions,causing strength increasing and toughness decreasing and broken under external force action.更多还原
