Effect of Hot Rolling Parameters on Excess Phase Precipitation in Two-Phase Ferritic-Martensitic Steels
- 34 Downloads
Results are given for studying the effect of hot rolling parameters on morphological features of the structure and precipitation in hot rolled products destined for further cold rolling and heat treatment in a continuous annealing line. Temperatures for the end of rolling and coiling are varied with hot rolling of a laboratory melt. Depending on the combination of temperatures for the end of rolling and coiling temperature, the amount of precipitates and their preferred location vary.
