Effect of semifinished rolled product cooling rate during controlled rolling on the condition of microalloyed steel hot-worked austenite, final microstructure, and mechanical properties. Part 1. Study of the Effect of Semifinished Rolled Product Cooling Rate on Ferrite-Pearlite Microstructure Formation

The effect of cooling rate is studied under laboratory conditions for semifinished rolled product in a temperature range of the order of 1000–850°C using controlled rolling technology on the condition of hot-worked austenite, grain refinement in the final microstructure, and set of mechanical properties for low-carbon microalloyed steel.
