| 摘 要： | 分别采用排水法、闪光法和比较法测定了55CrMo钢的室温密度、热扩散率和比热容，并计算得出了该钢的导热系数。结果表明：随着温度的升高，55CrMo钢的比热容总体上呈上升趋势，而热扩散率和导热系数则以相反趋势变化，且该三个热物性参数均在相变区内有所波动；测定结果为开展55CrMo钢感应加热淬火过程的有限元模拟提供了重要的试验数据。

| Abstract: | The room temperature density,thermal diffusivity and specific heat of 55CrMo steel had been measured by displacement way,flash method and comparison method,respectively.And the heat conductivity of the steel was also be calculated.The results show that the specific heat of 55CrMo steel increased generally with the increase of temperature,while the thermal diffusivity and heat conductivity changed in a contradictory tendency.All these these parameters fluctuated during the temperature zone of phase transformation.The experimental results provided some important data for the numerical simulation of induction quenching process of 55CrMo steel. |
