Flash~R Bainite: Room Temp Stamping 1500 to 1800MPa Structural and Energy Absorbing Components to <2T Bend Radii and the Coil-to-Coil Production Equipment

摘要

Flash? Bainite Processing employs rapid thermal cycling (<10s) to strengthen commercial off the shelf (COTS) steel sheet, plate, and tubing into advanced high strength steel (AHSS). In a continuous process, induction technology heats a narrow segment of the steel cross section in just seconds to atypically high temperatures (1000-1300°C). Quenching substantially immediately follows. Flash~R Processing optimizes the inherent heterogeneity of steelmaking to form a complex intra-granular multi-chemistry, mixture of bainite, martensite, and other morphologies. Carbon migration and carbide dissolution are controlled by limiting time in the austenitic range. Unlike conventional heat treating, homogeneity is intentionally avoided.
