摘要：

Effect of cooling rates on the microstructure and properties of MA steel processed through forging route was investigated. The steels used were medium carbon microalloyed steel with varying vanadium and aluminum percentages. Specimens were heated at 1100 °C for 30 minutes and forging was carried out. The room temperature tensile strength was measured using an Instron machine at a crosshead speed of 1mm/minute. The pearlite grain size, volume fraction of ferrite, and pearlite were determined by using mean linear intercept method and point counting. Results show that vanadium addition raised strength and hardness by precipitation strengthening and by refining the pearlite.
