Integration Of Hadfield Steel Into Modern Body Armor, Jason T. Fridlund
Integration Of Hadfield Steel Into Modern Body Armor, Jason T. Fridlund
ME 4133/6133 Mechanical Metallurgy
The increased lethality of recently fielded projectiles mandates a proportional escalation in armor performance. Recent advancements in ceramic technologies have allowed designers to incorporate harder but more brittle materials into hard armor designs to defeat yet more capable penetrating projectiles. Ceramics suffer from the feature of shattering, however, even when impacted by threats below their design parameters. While this shattering mechanism is used effectively to dissipate energy from high-energy rifle projectiles, it is wasted on low-energy projectiles, and can result in easily damaged lifesaving gear, both of which are undesirable in combat. In contrast, steel body armor has been used …

AISI 1020 is widely used in many different industries due to its high strength, high ductility, high machinability, and good weldability. AISI 1020 has a number of applications. Low carbon steel can be used on a macroscale to build bridges, and low carbon steel can be used on smaller scales such as Lawnmower blades. Low carbon steel is the material of choice for lawn mower blades because of its ability to bend before it breaks. The ductile attribute of low carbon steel also has many other benefits.
