On the Processing of a Powder Metallurgy Low-Cost Ti Alloy via Different Induction Sintering Strategies

Reducing the cost of Ti alloys, both from a processing and compositional point of view, is a pathway forward for harnessing more extensively the industrial and environmental benefits associated with their uses, and it is an outstanding manufacturing challenge. Thus, this study investigated the manufacturing of a low-co...

Gas atomization for metal powder production in additive manufacturing: A review

Gas atomization is a key technology for producing high-quality metal powders, widely adopted in additive manufacturing and other powder-based industries due to its versatility and productivity. Its complexity, such as intense gas–liquid momentum exchange, thermal gradients in solidification, and multiple influencing fa...

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

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...

Physical property of 925 sterling silver metal injection molding and morphology of brown parts under varying solvent-based debinding conditions

This research aims to study the physical properties of raw parts produced using Metal Injection Molding (MIM), an advanced manufacturing process suitable for the industrial-scale production of highly complex, small, and high-precision three-dimensional metal parts. However, applying this technique to precious metals, e...

Production of in-Situ Al–Si functionally graded materials (FGMs) from A390 alloy

Abstract Although hypereutectic A390 (Al–Si–Cu) alloys are widely used in engine liners due to their superior wear resistance, conventional casting methods fail to provide the functional gradient required by internal combustion engines – specifically, high hardness at the inner surface and toughness at the outer surfac...
