“…The "austenite reverted transformation" (ART) heat treatment was adopted by the majority of medium Mn-content steels [18][19][20], but it was proven to be not applicable to the experimental steels, thus, a more convenient quenching and tempering (Q&T) proposed by Cai [21,22] was introduced. Firstly, the as-hot-rolled samples were annealed in the two-phase region for 1 h, followed by an immediate water quenching.…”

“…For steels containing 5 to 12 pct Mn, intercritical annealing, following the cold rolling of the martensitic microstructure, is investigated as a means of stabilizing the austenite by carbon and Mn partitioning. [7][8][9][10][11][12] The retained austenite fraction and stability depend, therefore, on the intercritical annealing temperature and time.Solute partitioning during intercritical annealing in medium-Mn steels has been investigated recently. Most of the research work is concerned with experimental determination of austenite volume fraction and composition.…”

“…Figures 12 and 13 present the lines of the diffratograms of the exposed surfaces of each test body of the materials ASTM A178 and ASTM A516, respectively, which show an incidence of ferrite α with greater intensity in the 45 degree angle (plane 110), but also in the angles of 65 degrees and 83 degrees (planes 200 and 211) which, according to Cai et al 19 show to have a greater presence of ferrite α in these materials. The presence of austenite γ occurs more discreetly, being recorded a line in the 43 degree angle (plane 111).…”

“…According to Cai et al 19 the main peak of cementite was observed at 44 degrees, and may be superimposed on the peak of the ferrite α (45 degrees), or absent, due to the technical limitation of X-ray diffraction when there is a small presence of phase in the matrix of these steels.…”
