Grain-refining of wire arc additive manufactured aluminum alloy with Nb powder addition

Nb powder with an average diameter of 15 μ m was added to the molten pool during wire arc additive manufacturing of 5B06 aluminum alloy. The unmelted Nb with high melting point and the in-situ alloying of Al _3 Nb acted as heterogeneous nucleation core. The fine equiaxed grains with a diameter less...
