| 摘 要： | Introduction Tungsten-copper alloy powders are used in many fields on account of the high electric and thermal conductivities of copper and high melting point of tungsten. W-Cu pow-ders, as prepared conventionally by means of infiltration, has the disadvantage of inhomogeneity in microstructure, and are difficult to work with after sintering. Increasing the particle activity of these powders tends to accelerate the sintering process, lower the sintering temperature and improve their properties…
