Abstract: Rapid investment casting with additively produced molds can offer excellent surface finishes, tight dimensional tolerances, and complex geometries for high-performance metal parts in a rapid fashion. However, there is a ...

Abstract: High-strength Al-Zn-Mg-Cu alloys such as AA7075 have drawn considerable attention and interest from both industry and academia owing to their high-specific strengths and good fatigue resistance. Wire-arc directed energy ...

Abstract: Arc welding of dissimilar aluminum alloys is in high demand in industry but often challenging in practice. Dissonant material properties between the base metals often lead to solidification cracking in the weld metal upon ...
