Abstract

The grain refinement effects and the ageing behaviour of aluminium alloys have been studied on the basis of OM, EPMA, FESEM, SEM, TEM, hardness measurements and mechanical properties. Grain refinement markedly achieved due to effectively consider at variable scandium contents (eg. hypereutectic composition) in cast aluminium alloys. The nanoparticles are fully coherent in matrix and its low lattice misfits (1.5%) caused well strong interaction with defects and dispersive characteristic. These alloys potentially revealed nanosized precipitates namely GP-zones, ή/η and Al₃Sc (L1₂) particles. The TEM micrographs revealed homogeneous distribution of nanoparticles after T₆ treatment and measured nanosized Al₃Sc particles (30-50 nm) after FSP. The FSP has potentially refine grains which is known to Zener pinning mechanism due to inhibit grain growth. Notably, FSP had been measured after T₄+FSP+Aged at 140°C for 2h (SFA), and related mechanical properties significantly achieved likely UTS of 329 MPa, ductility of 8.9%, hardness of 147.8HV and K_IC of 3.42-32.6 MPa√m in SZ, but fracture strength and ductility decline drastically in high scandium contents (0.87 wt.%) about 178 MPa and 4%, respectively. The aim is to determine the fracture strength for dispersive nanosized particles during FSP and subsequently TEM and SEM fractography analysis.
