Description

The effects of hot-pressing parameters on the microstructures and properties of B4C pellets were studied. The experimental results showed that the density and mechanical properties of B4C specimens increase with pressure and the porosity decreases. Hot pressing temperature has two concomitant effects. Firstly, the density, grain size and mechanical properties increase with sintering temperature, and secondly, grains grow remarkably above 2373K, so that the flexural strength of B4C specimens decreases. The grain size of nonstoichiometric boron carbide is smaller than that of the stoichiometric one after hot-pressing due to the presence of free boron or free carbon. The thermal properties are depending on the density and hot-pressing temperature. (author)
