摘要：

The　vertical　sections　of　Fe-10%Cr-B-xAl-C　quinary　system　with　different　aluminum　contents,　the　effect　of　aluminum　content　on　the　change　trend　of　phase　content　in　Fe-10%Cr-1.5%B-Al-0.3%C　quinary　system　at　900℃　and　the　equilibrium　solidification　processes　of　Fe-10%Cr-1.5%B-2%Al-0.3%C　alloy　have　been　calculated　by　use　of　Thermo-Calc　software.　The　Fe-10%Cr-1.5%B-2%Al-0.3%C,　Fe-10%Cr-1.5%B-4%Al-0.3%C　alloy　were　chosen　to　be　studied　by　experiment.　The　phase　transition　temperatures　were　measured　by　DSC　and　the　microstructure　and　the　phase　types　were　detected　by　SEM-EDS　and　XRD.　The　results　indicate　that　calculated　phase　diagrams　agree　well　with　the　experimental　results　and　further　prove　the　thermodynamics　database　of　Thermo-Calc　software　to　be　reliable　and　it　can　be　used　to　help　design　the　alloy　composition　and　heat　treatment　process.　©　2015,　Chinese　Mechanical　Engineering　Society.　All　right　reserved.
