Influences of High-Temperature Diffusion on the Homogenization and High-Temperature Fracture Behavior of 30Cr1Mo1V

High cycle fatigue behavior of a dissimilar metal welded joint in ultra-supercritical steam turbine rotor

“…The microstructures of BM-1 are ferrite and tempered sorbite, as shown in figure 4(a). It is well known that ferrite/sorbite in this kind of steel is beneficial to improve elevated temperature strength and creep property [26]. Figures 4(b) and (c) display the microstructure characteristics of BL and WM.…”

Dissolution of Large‐Sized Primary Carbides in 6Cr13 Continuous Casting Slabs during High‐Temperature Homogenization

“…[10] The high-temperature homogenization treatment can reduce the segregation of dendrites of continuous casting slabs, homogenize the alloying elements, and improve the morphology, size, and distribution of large-sized primary carbides. [11][12][13][14] Zhu et al found that there was almost no change after the formation of primary carbides in the research of precipitation of carbides in high-carbon martensitic stainless steel. And they noticed local melting near the M 7 C 3 carbide in high-temperature in situ observations.…”

Evolution of Eutectic Carbide during M7C3/M23C6 in situ Transformation in Martensitic Stainless Steel

“…[5] Improving the solidification process [6] and adding Nb, Ti, rare earth, and other alloy elements [7][8][9][10][11] could reduce the size and improve the morphology of eutectic carbides but could not completely eliminate these eutectic carbides. Homogenization [12][13][14][15][16] and high-temperature deformation treatment [17,18] could improve element segregation and promote the dissolution or decomposition of large carbides. However, the eutectic M 7 C 3 carbide in high-carbon martensitic stainless steel remained stable even when the temperature increased close to or up to the solidus temperature of the steel.…”
