Kinetics of Austenite Transformation During Thermomechanical Processes

Microstructural evolution of delta ferrite in SAVE12 steel under heat treatment and short-term creep

“…9 [30]. Heat treatment results show that the dissolution of delta ferrite accelerates as the temperature increases.…”

“…The 'TTT' diagram of dissolution of delta ferrite[30]. Microstructure of delta ferrite after creep exposure at 600°C for 1100 h: (a) the bright field image, and (b) the dark field…”

Microstructure and Mechanical Properties of J55ERW Steel Pipe Processed by On-Line Spray Water Cooling

“…The effect is increased with the increase of deformation. Furthermore, it has been reported that the ferrite mainly nucleates at the boundaries of the austenite grains and defects [31]. The defects generated by deformation in the austenite increase the amount and rate of nucleation along the grain boundaries and refine the grains of ferrite and pearlite.…”

Determination of Upper Limit Temperature of Strain-induced Transformation of Low Carbon Steels.

“…13,16,17) The work of Ouchi et al 17) indicated that for Si-Mn steels the A r3 changed slightly as deformation temperature changed when the deformation temperature was above 880°C. In present work, the relationship of A r3 and deformation temperature in temperature range of 830-1 000°C was investigated.…”

“…In recent years, a lot of investigations [1][2][3][4][5][6][7][8][9][10][11][12][13][14] about the grain refinement through TMCP have been carried out. For plain low carbon steel, the strain induced transformation played important role in ferrite grain refinement.…”
