Cast　Fe-10Cr-1.5B-2Al　alloy　was　quenched　at　different　temperatures.　The　effects　of　quenching　temperature　on　microstructure　and　hardness　and　wear-resistance　of　Fe-10Cr-1.5B-2.0Al　alloy　were　investigated　by　means　of　the　optical　microscopy,　the　scanning　electron　microscope,　X-ray　diffraction,　energy　dispersive　spectrometer,　Vickers　hardness　and　Rockwell　hardness　tester,　and　the　MM-200　block-on-ring　wear　testing　machine　under　dry　friction　condition.　The　results　indicate　that　the　as-cast　microstructure　of　Fe-10Cr-1.5B-2.0Al　alloy　consists　of　ferrite,　pearlite　and　net-like　eutectics　which　are　distributed　in　the　grain　boundary.　The　eutectics　mainly　include　herringbone　M2B　and　chrysanthemum　M-7(C,B)(3).　The　matrix　gradually　turns　into　single　martensite　with　the　increase　of　the　quenching　temperature.　The　type　of　borocarbides　has　no　obvious　change　after　quenching.　The　netlike　boride　almost　totally　fractures　and　transforms　from　the　fish-bone　structure　to　the　graininess.　There　is　some　retained　austenite　in　the　quenched　structures　when　the　quenching　temperature　is　more　than　1100　degrees　C.　When　the　quenching　temperature　is　in　a　range　of　1000　degrees　C　to　1100　degrees　C,　the　hardness　and　wear　resistance　show　a　sharp　increase　with　an　increase　of　temperature,　and　show　a　slight　decrease　after　surpassing　1100　degrees　C.
