RISDirected Energy Deposition of Zirconia-Toughened Alumina Ceramic: Novel Microstructure Formation and Mechanical Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Over the past two decades, a considerable amount of work has been done on zirconia-toughened alumina (ZTA) to take advantage of the recognized toughening effect induced by ZrO2. In fabricating customized or complex-shaped ...
Ultrasonic Frequency Effects on the Melt Pool Formation, Porosity, and Thermal-Dependent Property of Inconel 718 Fabricated by Ultrasonic Vibration-Assisted Directed Energy Deposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultrasonic vibration-assisted (UV-A) directed energy deposition (DED) has become a promising technology to improve the as-built quality and mechanical performance of metal parts. Ultrasonic frequency, a critical parameter ...
Ultrasonic Vibration-Assisted Laser Engineered Net Shaping of Inconel 718 Parts: Microstructural and Mechanical Characterization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser engineered net shaping (LENS) has become a promising technology in direct manufacturing or repairing of high-performance metal parts. Investigations on LENS manufacturing of Inconel 718 (IN718) parts have been conducted ...
