The　effect　of　vanadium　on　the　microstructure　and　properties　of　Fe-Cr-C　hardfacing　alloys　were　investigated　with　four　kinds　of　hardfacing　alloys　that　the　mass　fraction　of　vanadium　was　0.73%,　2.3%,　3.1%,　4.1%　respectively.　The　effects　of　vanadium　element　on　microstructure　and　mechanical　properties　were　analyzed.　The　results　indicate　that　metal　matrix　of　hardfacing　alloys　transform　from　austenite　to　austenite　and　martensite　with　increasing　vanadium　content.　The　metal　matrix　changes　into　martensite　completely　when　vanadium　content　is　up　to　4.1%.　The　shape　of　primary　carbides　changes　form　long,　bulk　hexangular　to　spherical　and　irregular,　large　numbers　of　secondary　carbides　precipitates　and　disperses　in　metal　matrix　of　hardfacing　alloys　with　the　increase　of　vanadium　content.　The　hardness　and　wear　resistance　also　enhance　with　the　increase　of　vanadium　content.
