The Influence of Bainite on Retained Austenite Characteristics in Si-Mn TRIP Steels

Mechanical Behavior and Microstructure of High Carbon Si–Mn–Cr Steel with Trip Effect

“…1,2) Consequently, the retained austenite can be transformed into martensite during the plastic deformation promoting a tensile strength increase and ductility without losing the formability capacity. 4,5) This is the principle of TRIP effect; originally published by Zackay et al 1) and it has been subject of many studies. [1][2][3][4][5] The TRIP-aided steels have been developed as steel sheet for automotive reinforced members.…”

Effects of Aluminum on Delayed Fracture Properties of Ultra High Strength Low Alloy TRIP-aided Steels

“…At present, TRIP-aided steels with polygonal ferrite [2][3][4][5][6][7] matrix (TDP steel), bainitic ferrite 8) matrix (TBF steel) and annealed martensite 9) matrix (TAM steel) have been developed. Particularly, TBF steel is able to obtain a high tensile strength more than 1 000 MPa.…”

“…The TRIP-aided steel possesses excellent formability. [2][3][4][5][6][7][8][9] Therefore it is expected to be used for the automotive impact members and center pillars.…”

Effects of Nitrogen on the Mechanical Properties of Cold Rolled TRIP-aided Steel Sheets

“…22) Therefore the mechanical properties and the morphology in TRIP-aided steels are found strongly dependent on the austempering condition. 7,10,23) The precipitates can also affect the transformation and grain growth in the TRIP-aided steels during the annealing process. In order to clarify the effect of precipitate on the morphology and mechanical properties, it is necessary to form precipitates without solid solution of added elements.…”
