In this study, the strength characteristics and microstructure of tungsten materials were investigated. Tungsten materials were fabricated using the combination of solid state sintering process and applied pressure. Tungsten powder was sintered at the sintering temperature of 1700 ℃ or less. Tungsten materials showed good flexural strength at ths sintering temperature of 1500 ℃, accompanying the creation of fine grain and the micro pore. However, tungsten materials fabricated at the sintering temperature above 1600 ℃ showed coarsening of tungsten grains and reduce flexural strength.
