摘要：

In-situ　MgB2/Fe　tapes　were　fabricated　by　the　powder　in　tube　(PIT)　technology　using　Mg　and　B　powders.　The　tapes　were　sintered　by　both　an　advanced　spark　plasma　sintering　(SPS)　and　a　conventional　vacuum　furnace,　respectively.　The　effects　of　these　two　sintering　routes　on　the　properties　of　the　MgB2　tapes　were　investigated　by　the　analysis　of　XRD,　SEM　and　the　magnetic　Jc　measurements.　It　was　shown　that　at　10K,　0T,　the　magnetic　Jc　value　of　the　tape　sintered　using　SPS　machine　at　800°C　for　15min　under　30MPa　were　close　to　106A/cm2,　which　was　higher　than　that　of　the　tapes　annealed　at　700°C　for　2h　under　pressureless　vacuum　condition.　It　was　found　that　the　density　and　the　homogeneity　of　the　MgB　2　core　were　strongly　improved　using　SPS　sintering　process,　which　explained　why　the　MgB2　tapes　sintered　by　SPS　method　have　a　higher　Jc　value.　Further　enhancement　of　Jc　in　the　tapes　is　expected　for　the　understanding　of　the　SPS　sintering　mechanism.
