压力对Mg-Al-Cr-O自蔓延系统反应温度及反应速度的影响

The Effect of Press on Temperature and Rate of SHS in the System Mg-Al-Cr-O

通过对自蔓延系统的不同压力下的试样点燃温度和反应速度的比较发现，随着制备试样压力的增加，系统的自蔓延点燃温度升高，反应速度下降；相对温度而言，压力对该系统自蔓延反应速度的影响更明显。这一情况为更有效的控制自蔓延过程提供了思路。

By making a comparison of combustion temperature and propagating rate of samples which are developed in different press in the system Mg -Al - Cr - O of SHS, we have discovered that the temperature of SHS rises and the propagting rate reduces with press rising. The press is more obvious influence to the temperature than the Propagaing rate. This result provides a new thinking for us in order to control theprocess of SHS effectively.
