摘要： A process for making steel armor products for use, for example as body armor. The steel armor product made has a compound curve and is made from a flat blank of armor steel by high-temperature annealing an armor steel blank to slightly above its austenitizing temperature, then followed by a slow, temperature-controlled cooling it, over-pressing the annealed blank to a first configuration so it springs back to a second configuration approximating the desired product shape when released from the press, and then heat-treating the product back to its austenitizing temperature, quenching it, and tempering it at a low temperature. The tool is conveniently made by lamination, using a series of thin plates of tool steel each cut to produce an approximation of the desired die.

摘要： A method for consolidating a pre-form made of powder, comprising: (a) placing the pre-form between smart susceptors; (b) heating the smart susceptors to a leveling temperature by applying a varying low-strength magnetic field having a magnetic flux that passes through surfaces of the smart susceptors; (c) applying consolidation pressure to the pre-form at least during a time period subsequent to the temperature of the smart susceptors reaching the leveling temperature; and (d) while consolidation pressure is being applied, applying a pulsed high-strength magnetic field having a magnetic flux that passes through a surface of the pre-form. The strength and pulse rate of the high-strength magnetic field are selected so that the crystallographic phase of the pre-form will rapidly oscillate at a substantially constant temperature. The pulsed high-strength magnetic field is applied sufficiently long that superplasticity of the pre-form is attained during phase oscillation.

摘要： A steel has a tensile strength of 850 to 1700 MPa, a yield ratio of at most 80%, and a penetration border energy ratio of at least 2.0 relative to the penetration border energy of a reference steel JIS SS400 (corresponding to ASTM A36) of the same thickness. The steel can be produced by first effecting a heat treatment 1 on an unstable austenitic steel; then effecting, at least once, one or more or any combination of the heat treatment 1 and a heat treatment 2 on the steel; and then finally effecting the heat treatment 2 on the steel. Heat treatment 1 heats the unstable austenitic steel to at least the Ac3 transformation temperature and then water-cools the steel to a temperature below 350° C. Heat treatment 2 heats the steel to a temperature between Ac3 and Ac1 transformation temperatures and then water-cools the steel to a temperature below 350° C.
