An assembly based on the deposition and pressureless sintering of successive silver layers on an Aluminum Nitride heat sink is studied in this paper. Sintered silver layers act as die attach, current tracks and adhesion layer on the ceramic. Compared

WC–Co materials are usually produced through a powder metallurgy route, including a liquid-phase sintering step in the 1350°–1450°C temperature range. However, it is well established that a large part of sintering already occurs in the solid-st

Publikováno v: Materials Science and Engineering: A. :525-531

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 electro
