The　solidification　process　and　solidification　structures　of　Fe-B-C　alloy　containing　1.4%-2.0%　B　and　0.4%-0.6%　C　were　researched.　The　change　of　microstructures,　mechanical　properties　and　wear　resistance　of　the　alloy　at　different　quenching　temperatures　were　also　studied.　The　results　show　that　the　solidification　structures　of　Fe-B-C　alloy　consist　of　borides　such　as　Fe(2)B,　Fe(3)(C,　B)　and　Fe(23)(C,B)(6)　and　metallic　matrix　such　as　martensite,　pearlite　and　ferrite.　The　part　of　boride　network　is　broken　and　there　is　no　new　phase　after　quenching.　The　matrix　transforms　into　the　single　martensite　completely　and　the　hardness　exceeds　55　HRC.　The　hardness　of　Fe-B-C　alloy　increases　while　the　impact　toughness　has　no　obvious　change　with　increase　of　the　quenching　temperature.　Under　the　conditions　of　static　load　pin-on-disc　wear　and　dynamic　load　impact　wear,　Fe-B-C　alloy　has　excellent　wear　resistance　and　the　quenching　temperature　has　no　marked　effect　on　the　wear　resistance.
