摘要: In this paper the feasibility of fabricating W-Cu composite by hot-press has been studied and best parameters for hot-pressing were acquired. W/20 vol%Cu was successfully prepared process, in which at first powder tungsten copper, containing 20% vol copper mixed a ball mill 3 h rotation speed 200 rpm. Then powders hot-pressed compact pressure 30 MPa temperatures 1,250°C, 1,350°C, 1,450°C. The composites made have investigated revealed making with good properties included density, hardness, modules elasticity, flexural strength, microstructure. Also, sample 1,450°C possesses better properties, its microstructure showed matrix reinforcement separately; X-ray diffraction patterns that no compound formed between W Cu.
