冲击温度是表征材料Hugoniot状态性质的一个重要参量.但金属及合金冲击温度的测量是一个非常复杂的问题,国际上关于这方面实验数据的报道也还只是近几年的事.由于铁及其合金的冲击温度数据对于确定地心的热力学状态具有重要意义,所以尤其引人关注.本文报道了利用光谱辐射法测得的45号钢(碳的含量为0.42%～0.50%)的冲击温度数据.
The impact temperature is an important parameter to characterize the state of the material Hugoniot, but the measurement of metal and alloy impact temperature is a very complex issue, and the international reports on the experimental data in this area are still only in recent years. The impact temperature data of alloys are of particular interest for determining the geothermodynamic state of geocenters.This paper reports the impact temperature data of 45 steel (carbon content 0.42% -0.50%) measured by spectral radiance method .
