This irreversible process influences material’s macro property directly.
When the constant stress of rock is far less than the material yield strength, even if the temperature is high, the material damage will be difficult.
So in this experiment we cannot observe material damage as it is heated to a certain temperature.
When the material is under the actions of loading and temperature, the material micro-structure organizations, inclusions, such as grain size and micro-crack, crack growth are related to fracture.

TiB2-(Ti,W)C Eutectic Composite Ceramics Prepared by Combustion Synthesis under High Gravity Xuegang Huang, Long Zhang, Zhongmin Zhaoa, Chuanzeng Pan and Guanling Su Laboratory of Special Ceramics, Institute of Advanced Materials, Mechanical Engineering College, Shijiazhuang 050003, China a zhaozm2007@Yahoo.cn Keywords: TiB2-(Ti,W)C composite; Combustion synthesis; High gravity; Structure transformation Abstract.
Experimental Raw materials were made up of Al, Ti, C, B4C, WO3, CrO3 and ZrO2(4mol%Y2O3) blends.
According to the early achievement of preparing TiC-TiB2 composite ceramics, the (B4C+Ti+C) of 80% was taken as the main system, and TiC-40mol% TiB2 was selected as the eutectic compositon of the materials based on Eq. (1).

Influence of Surface Chemical Groups and Content of Carbon Nanotubes on Electrical Property of Epoxy Resin Composites Shaofeng Lina, Cai Jiangb, Jianwei ZhangC and Dazhi Jiangd* and Su Jue Department of Materials Science and Engineering, National University of Defense Technology, Changsha, Hunan, 410073, China Email: alinsfbgg@163.com, bjane19871025@163.com, cjwzhang.nudt@gmail.com, djiangdz@nudt.edu.cn, esuju-nudt@nudt.edu.cn Keywords: Carbon nanotubes, Epoxy resin, Dispersion, Chemical groups, Electrical conductivity.
Introduction Due to the graphite like structure, carbon nanotubes (CNTs) have attracted much attention of researchers for particular mechanical, thermal and electrical properties, which could be used in insulating polymer matrices and structural materials [1-4].
On the other side, epoxy resin shows lots of interesting characteristics, applied in electronics, printed circuit boards, packaging materials, and electrical insulators [5, 6].
