In　this　study,　chromium　carbide-nickel　composites　were　fabricated　by　mixing　pure　Cr3C2　and　Ni　powders　at　1250,　1275,　1300　and　1325　°C　for　1　h.　The　effects　of　the　Ni　content　on　the　microstructures　and　mechanical　properties　of　these　composites　were　researched.　Both　Cr3C2　and　Cr7C3　showed　a　well-defined　crystallographic　orientation.　Two　groups:　(002)Cr3C2//(004)Cr7C3　and　[2¯10]Cr3C2　//　[2¯10]Cr7C3　were　observed.　The　porosity　of　the　specimens　first　declined　and　then　risen　slightly　with　an　increase　in　the　Ni　content.　The　micro-hardness　of　the　specimens　showed　an　opposite　trend.　The　bending　strength　and　fracture　toughness　of　the　specimens　first　risen　with　an　increase　in　the　Ni　content　and　then　decreased,　thus　changing　the　fracture　mechanism　from　inter-granular　fracture　to　trans-granular　fracture.　The　optimal　temperature　was　1300　°C　and　the　composite　with　20　wt%　Ni　showed　the　best　mechanical　properties.　©　2019
