HIGHLIGHTS
- who: Sheng Huang and colleagues from the College of Materials and Metallurgy, Guizhou University, Guiyang, China have published the article: Effect of Thermal Simulation Process on Microstructure of Seismic Steel Bars, in the Journal: Materials 2022, 3438 of /2022/
- what: The main reason was the effect of microalloying element Nb/V/Ti and the hot rolling process.
SUMMARY
The key factors are the formation of fine austenite grains during hot deformation and transformation of undercooled austenite into fine ferrite grains during final cooling. Rolling ratio, rolling temperature, cooling method, final cooling . . .
