摘要
This paper obseved that Co phase distribiton in 3m%, 6m %、11m%, 15m%、20m% cemented carbide,residuary co phasedistribition on the original plane surface after acid olissolved,Co phase distribition in the unfiren alloy,Co phase olistibition inthe compact,the pore and the interstice in the alloy,Co pool, metallic intermixture,the carburizition, the decarburigation,thesolution and the repricipition,grain boundary melt,and cubic staking state by SEM appearance. It had obseved sometime,thatxli phase distribition in WC-Nil0m% alloy and Fe phase distribition in WC-Fe10m% alloy. It had reviewde that five struc-ture theory, i. e. skeletm hypothesis, this firm hypothesis, revisory skeleton hypotbesis, network hypothesis and randomstacking structure.
