Effect of Heat Treatment on the Evolution of Structural and Phase State in Wire Electron Beam Additively Manufactured Al–12Si Alloy
The effect of heat treatment on the structural evolution, phase transformation, and mechanical strength of Al–12Si obtained using wire electron beam additive manufacturing has been investigated. The as-built Al–12Si alloy was characterized by structural inhomogeneities in the form of interlayer bands with coarsened Si particles resulted from cyclic reheating of the solidified metal. Quenching the as-built samples resulted in the increase of the volume fraction of Al/Si eutectics by 9% with simultaneous refinement of Fe-containing particles. This structure allows obtaining the combination of strength and plasticity better than that of the asbuilt sample. Annealing leads to coarsening of both Si and Fe-containing particles, thereby increasing the Al/Si volume fraction and impairing the mechanical characteristics.
