ThyssenKrupp Steel, Germany, and JFE Steel Corp., Japan have developed a multiphase steel

ThyssenKrupp Steel, Germany, and JFE Steel Corp., Japan have developed a multiphase steel said to provide a minimum strength of 780 MPa (113 ksi) and 40% higher elongation than conventional high-strength steels. Designated TP-N 68/78, its high strength and good formability are attributed to a bainitic-ferritic microstructure with embedded retained austenite in combination with nanometer-size precipitates.
