RISHeat Treatment-Controlled Wear Performance and Tool Life Assessment of H13 Steel for Joining CuCrZr Plates Using Friction Stir Welding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Friction stir welding (FSW) is a robust solid-state joining process increasingly applied to high-melting-point materials such as Cu, Fe, Ti, and their alloys, beyond conventional Al and Mg systems. However, tool ...
Strategies to Mitigate Interlayer Porosity in the Laser-Directed Energy Deposition Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Laser-directed energy deposition (L-DED) offers unique advantages for fabricating large-scale metallic components and repairing high-value parts. However, recurring interlayer porosity, particularly while depositing ...
Laser Surface Polishing of Additively Manufactured Components Via Beam Shaping: Influence on Surface Topography, Microstructure, and Mechanical Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Additively manufactured components often exhibit poor surface quality due to partially fused powder particles and overlapping tracks. To overcome this limitation, laser surface polishing (LSP) was applied to ...
