In　this　work,　a　new　type　of　high　entropy　alloy　(HEA)　composite　Fe18Ni23Co25Cr21Mo8WNb3C2　was　prepared　by　mechanical　alloying　(MA)　and　hot　pressing　sintering　(HPS).　Phase　transitions,　microstructure　characteristics,　and　tensile　properties　of　samples　were　analyzed.　During　the　MA　process,　a　powder　mixture　of　Cr-Mo　was　milled　to　synthesize　the　amorphous　alloy　powder　Cr(Mo)a.　Then,　the　mixture　of　amorphous　alloy　powder　Cr(Mo)a　and　other　elemental　powders　(Fe,　Ni,　Co,　W,　Nb,　and　C)　was　milled　to　obtain　the　HEA　powder.　This　HEA　powder　is　composed　of　single-phase　austenite　(gamma).　Finally,　the　HEA　powder　was　consolidated　using　HPS.　The　sintered　HEA　composite　contains　the　matrix　phase　austenite　A　and　second-phase　M　6　C　carbide.　The　precipitation　reaction　that　occurs　during　the　sintering　process　can　be　summarized　as:　gamma　-＞　A　+　M6C.　Tensile　properties　of　the　sample　sintered　at　1050　degrees　C　were　tested.　At　room　temperature,　ultimate　tensile　strength　and　elongation　are　similar　to　1452　MPa　and　similar　to　3.9%,　respectively;　at　650　degrees　C,　ultimate　tensile　strength　and　elongation　are　-　similar　to　795　MPa　and　similar　to　13.3%,　respectively.
