Processing of tungsten/copper materials from W–CuO powder mixtures

Abstract: In this study, processing of W–Cu materials from attritor-milled W–CuO mixtures is described. Reduction steps of powder compacts are investigated by TGA, dilatometry and XRD analyses. Morphological characteristics are observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Sintering of reduced powder with different compositions is analyzed by dilatometry and assembly of graded materials is briefly discussed. [Copyright &y& Elsevier]
