Exotherm-Assisted Additive Manufacturing of a High-Strength Multi-Principal Element Alloy

Innovative Additive Manufacturing of Ultrahigh-Strength and Heat-Resistant Aluminum Alloy.

Additive manufacturing (AM) advances the use of complex-geometry aluminum (Al) alloys for lightweight aerospace components. However, AM of high-strength Al alloys is challenging due to their inherent high susceptibility to cracking. Inoculating with scandium or zirconium effectively suppresses cracking in AM Al alloys...

Plasma Arc Assisted Additive Manufacturing Using Magnesium Alloys: A Review

Magnesium alloys have emerged as essential materials in biomedical applications due to their biocompatibility and biodegradability.

Electrochemical polishing of additively manufactured titanium alloys: a mechanism-to-parameter framework for process design

Additive manufacturing (AM) has expanded the use of titanium and its alloys in aerospace, biomedical, marine, and automotive components, but the rapid melting–solidification cycles inherent to AM leave characteristic surface defects—balling, partially melted particles, scan-track ridges, and near-surface porosity—that...

Metal additive manufacturing for high-performance electrical machines: a review

Achieving high power density and ultra-high efficiency in electrical machines requires overcoming the inherent 2D geometric constraints of conventional mass-manufacturing methods. In this context, additive manufacturing (AM) enables the fabrication of complex, highly integrated components and emerges as a transformativ...
