【摘要】 使用Gleeble 3800热模拟试验机,研究了不同应变速率和不同温度条件下,钒微合金化对高碳钢动态再结晶行为利奥氏体转变温度的影响。结果表明,钒微合金化能推迟高碳钢动态再结晶,大幅度降低奥氏体转变温度。依据试验数据计算,钒微合金化使高碳钢动态再结晶激活能增加12kJ mol^-1。更多还原

【Abstract】 The effect of vanadium microalloyed on dynamic recrystallization behavior of high carbon steel and austenite transformation temperature was investigated on a Gleeble 3800 thermal simulator at different strain rate and temperature conditions.The results indicate that dynamic recrystallization of high-carbon steel was delayed and austenite transformation temperature was decreased largely by vanadium microalloyed.The basis of test data,vanadium microalloyed made high carbon steel dynamic recrystallization activation energy increased 12kJ mol^-1.更多还原
