ATOM-PROBE RESULTS SUPPORT THE SKELETON MODEL FOR WC-Co

Abstract
WC/WC boundaries in WC-Co type cemented carbides have been analysed with the atom-probe instrument. The boundaries contained about half a monolayer of cobalt (or Co + Cr) and can therefore be described as grain boundaries with cobalt segregation. The results support the "continuous skeleton" mode1 of WC-Co
