THE REACTION BETWEEN Ni_(40)Mn_(30)Fe_(30) AND WATER-BEARING PYROPHYLLITE AT HIGH TEMPERATURE AND HIGH PRESSURE

本文对Ni40Mn30Fe30合金与在不同焙烧温度下得到的含水叶蜡石，在高温超高压下的反应进行了实验研究，温度测至1420℃，压力测至5．5GPa。研究了该反应进行的物理-化学机制，以及反应速率与温度、压力、含水量等参数的关系。对高压下物质迁移运动的固有特征进行了探讨。

This paper reports the experimental results of the reaction between Ni40Mn30Fe30 and water-bearing pyrophyllite at high temperature and high pressure. The experimental temperature andpressure were measured to be 1420℃ and 5. 5 GPa, respectively. In the experiment, the physicochemical mechanism of the reaction, the relationship between reaction speed and temperature, andpressure, the content of water, and the features of material movement uuder high pressure conditions were studied.
