压缩硬度

借助XRD进行相分析，对不同Fe含量的合金进行室温塑性、压缩性能和硬度测试；利用SEM对试样断口进行观察。

The phase is studied by XRD , room-temperature ductility , compress properties and hardness were investigated and the fracture surfaces were observed by SEM .

当压前含水率在50%左右时，压缩木的硬度、抗弯弹性模量和抗弯强度最大，回复率最小。冲击韧性随着压前含水率的增加而呈下降趋势。

When moisture content before compressed is about 50 % , compressed wood 's hardness , bending elastic modulus , bending strength is best , toughness show a tendency to drop with moisture content increase , wearability is the best when wood compressed under the full water stated .

石墨能提高复合材料的压缩强度，但硬度、拉伸强度和冲击强度下降。

Compression strength could be enhanced by filling graphite , but hardness , tensile strength and impact strength were decreased .
