(Nd1-xCex)(30)Fe69B　(x=0,0.1,　0.2,　0.3,　0.4,　0.5,　and　0.6)　alloys　were　prepared　by　inducting　melting,　and　the　effect　of　substitution　of　Ce　for　Nd　on　their　microstructure　and　intrinsic　magnetic　properties　were　investigated.　With　the　increase　of　Ce　content,　Curie　temperature　(T-c)　decreases　from　582.4　to　504.8　K,　saturation　magnetization　(M-S)　decreases　from　15.88　to　12.71　kGs,　and　anisotropy　held　(H-A)　decreases　from　67.4　to　52.7　kOe.　However,　the　reductions　of　the　intrinsic　magnetic　properties　are　relatively　gentle,　and　they　still　have　potential　to　be　prepared　as　permanent　magnets.　Moreover,　further　microstructure　observations　show　that　Ce　is　tending　to　diffuse　into　the　Nd-rich　grain　boundary　phase　instead　of　main　phase　during　the　substitute　process.　Such　aggregation　behavior　is　beneficial　to　fabricate　Ce　containing　magnet　with　high　M-S.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
