4 Conclusions

In the present study, scandium inoculated cast aluminium alloy surface layer was successfully fabricated by double passes FSP. The microstructure, tensile and fracture toughness properties were evaluated observing the matrix grains and dispersion of the second phases. The following results have been drawn below:(1)The grain refinement of aluminium alloy is achieved by the addition of inoculant particles (e.g. Al3Sc) in the form of Al–Sc master alloy during melt practise.
