Effect of normalizing and tempering temperatures on microstructure and mechanical properties of P92 steel

Ageing Effects on Room-Temperature Tensile Properties and Fracture Behavior of Quenched and Tempered T92/TP316H Dissimilar Welded Joints with Ni-Based Weld Metal

“…Figure 5 shows the detailed microstructure of the T92 region of the investigated weldment formed of homogenized and tempered martensite, typically consisting of tempered martensitic laths inside the blocks and packets structures within prior austenitic grains. In accordance with numerous research studies focused on normalized and tempered grade 92 steels (e.g., [6][7][8][9][10][11][23][24][25]), the phase composition of the T92 steel region of the investigated weldment in its initial QT PWHT condition consists of ferrite matrix and secondary phase precipitates, namely intergranular M 23 C 6 (M = Cr, Fe, . .…”

Evaluation of Workability on Microstructure and Mechanical Property of Modified 9Cr-2W Steel for Fuel Cladding by Cold Drawing Process and Intermediate Heat Treatment Condition

“…A typical tempered martensitic structure is produced by the tempering condition after normalizing. There is no recrystallization during the tempering heat treatment, and the strength decreases and the ductility increases due to dislocation recovery, but the previous austenite grain size is not affected [14].…”

“…As the normalizing temperature increases, compressive stress also increases. During the normalizing heat treatment, carbide is solubilized in the matrix and has a low fraction of precipitate, which increases the stress induced by carbon in the matrix [14]. When the as-drawn conditions were tempered at 760°C for 40 min, stress was reduced because the dislocation density decreased, and solute atoms in the matrix precipitated with a high fraction precipitate [14].…”

A through-process, thermomechanical model for predicting welding-induced microstructure evolution and post-weld high-temperature fatigue response

“…Heat treatment, microstructural and mechanical data from Barbadikar et al [20] was used in conjunction with the hardness model to devise an empirical heat-treatment-microstructure model which relates lath-width, L, to hardness, H, and prior-austenite grain size, d:…”
