Abstract:
The effect of heat treatment process on the microstructure and properties of casting Al-5.5Fe-4Cu-2Zn-0.4Mg-0.5Mn alloy were studied. It has been founded that, the mechanicals properties of casting Al-5.5Fe-4Cu-2Zn-0.4Mg-0.5Mn alloy improved significantly after solid solution and aging treated (T6), the tensile strength increased from 173.4MPa to 218.7 MPa. However the mechanical properties of the alloy after aging treated (T1) get less enhanced and the tensile strength only achieved 194.07MPa. The SEM and TEM analysis shows that solid solution treatment plays a role of dissolving the second phases in casting Al-5.5Fe-4Cu-2Zn-0.4Mg-0.5Mn alloy. After solution treatment the alloy was proceed with low-temperature ageing treatment, a large number of dispersively tiny phases precipitated in the matrix of the alloy, which exhibits strengthening action.
