The pre- cursor material and fusion process using the same may be utilized for forming an article that meets compositional specifications for aluminum 6061 alloy, while minimizing defects and meeting desired strength and ductility requirements. The fusion process may in- clude a leading energy beam for liquefying the precursor material to form a melt pool, and a trailing energy beam directed toward a trailing region of the melt pool. The trailing energy beam may be configured to enhance agitation and/or redistribution of liquid in the melt pool to prevent hot cracking, reduce porosity, or improve other characteristics of the solidified part. The method also may improve processing parameters, such as adjusting vacuum level to prevent volatilization of alloying elements.
