On cutting properties of the TiC-Cr3C2 base multi-component ceramic composites for carbon steel.

The Effects of ZrO2 or Tic on the Performance of the Alumina-Based Ceramic Cutting Tools

Two types of alumina-based cutting tools with compositions of 90 vol.% Al2O3+10 vol.% ZrO2 and 80 vol.% A12O3+20 vol.% TiC are produced by isostatic pressing and sintering technique. The effects of these additives on the mechanical properties and cutting performance of these materials are investigated. The tool life in both materials is examined under identical conditions on cutting a grey cast...

Effects of Multi-Walled Carbon Nanotubes on The Mechanical Properties of Glass/Polyester Composites

Excellent mechanical properties of carbon nanotubes (CNTs) make them outstanding candidate reinforcements to enhance mechanical properties of conventional composites. The glass/polyester composites are widely used in many industries and applications. Improving the mechanical properties of such composites with addition of CNTs can increase their applications. In this research, multi-walled carbo...

investigation of the electronic properties of carbon and iii-v nanotubes

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
