Effect of Rolling Reduction on Microstructure and Mechanical Properties of Plain Low Carbon Steel

摘要: In the present study, effect of cold-rolling for amount reduction in thickness ranging from 25% to 75% on microstructure and mechanical properties plain low carbon steel processed dual-phase ferrite-martensite starting was studied. As cold-rolling, elongated rolling direction more compressed with increasing strength also increased. After annealing at warm temperature 500°C, ultrafine grained obtained reduction. Moreover, it exhibited excellent 82% hardness 66.1% higher than as-received condition adequate uniform elongation 9.6%.
