摘要 在总结复相材料改善其热震稳定性的基础上主要列举了引入第二固相导致镁质耐火材料高温力学性能变化的典型例子。认为“第二固相原理”具有一定的普遍性,其本质是第二固相的引入优化了组织结构,或者提高了高温相直接结合的程度,或者形成了交织的网络结构和趋于更紧密的堆积,从而提高了高温力学性能。 On the basis of improvement of thermal shock resistence by multiphase materials, typical examples are illustrated that the introduction of the second solid phase resulted in the change of high-temperature mechanical properties of the magnesia refractory. In this paper a conclusion is reached that the principle on the second solid phase possesses popularity in that the introduction of the second solid phase optimizes The structure or upgrades the extent to which the high-temperature phases combine directly or forms the structure of interwoven network and tends to become more packed piles so that the high-temperature mechanical properties can be improved.
