Effect of caliber rolling reduction ratios on the microstructure and mechanical properties of 45 medium carbon steel

Tempered medium carbon steel with poor low-temperature toughness always limits its practical applications, while temper forming process can realize the strengthening-toughening aim by changing the microstructure. In this work, a grade 45 medium carbon steel was deformed with different rolling reduct...
