Characterization of microstructures and age hardening of Fe 1-2xAlxVx alloys
Abstract
<p>The Fe-rich corner of the Fe-Al-V system has shown phase separation into disordered A2 and ordered L2<sub>1</sub> phases. In a former work we model this ordering reaction by using ab-initio thermodynamics. The approach is now employed to suggest the Fe<sub>1-2x</sub>Al<sub>x</sub>V<sub>x</sub> alloys in order to reduce the Al content by increasing the addition of vanadium looking for a better ductility of the solid solution which can be afterwards strengthened by coherent L2<sub>1</sub> precipitates. Four alloys with compositions in the range 0.08 < X < 0.15 were studied. The phase transition temperatures and microstructures of the alloys were characterized by differential scanning calorimetry (DSC) and transmission electron microscopy (TEM), respectively. The region (A2 + L2<sub>1</sub>) occurs for 0.10 < X < 0.15 up to maximum temperature of 720 C, higher temperatures causes the appearance of (A2 + B2), B2 and (B2 + L2<sub>1</sub>) regions. The microstructure in the (A2 + L2<sub>1</sub>) region consists of nanosized precipitates of L2<sub>1</sub> phase in A2 matrix which morphology evolutes with temperature and ageing time. The hardness values, measured at room temperature, for the alloys with X < 0.125 and ageing temperature between 650 and 700 C are comparable to those obtained with other Fe-Al based alloys.</p>
