Notes:
Processing of W-Cu graded materials from attritor-milled W-CuO mixtures is described.The powder reduction steps are investigated by TG and XRD analyses and by microstructuralobservations (SEM, TEM). Sintering of reduced powder with different compositions is analysed bydilatometry. Sintering behaviour of the graded component processed by co-compaction of a10/20/30wt%Cu multi-layer material is briefly discussed. Liquid Cu migration is observed andsmoothes the composition gradient. Perspectives to control this migration are discussed
