莫来石基陶瓷材料的压痕硬度

Indentation Hardness of Mullite Based Ceramics

研究了莫来石基陶瓷材料的压痕硬度特性，以Ｆｒｏｈｌｉｃｈ等人提出的经验公式为基础，对实验数据进行了分析，提出了一种确定材料真实硬度的简便方法，并讨论了压痕弹性恢复对真实硬度实测值的影响．

The indentation hardness characteristics of mullite based ceramics were studied. Based on the empirical equation proposed by nohlich et al., the experimental results were evaluated and a simple method to determine the true hardness of material was proposed. The effect of elastic recovery of indentation on the measured true hardness was also discussed.
