Advanced Machining and Surface Engineering of Hard Alloys and Ceramics
This research community focuses on the precise cutting, grinding, and polishing of difficult-to-machine materials, such as titanium alloys, nickel-based superalloys, and silicon carbide ceramics, to achieve high surface quality and minimal tool wear.
The work centers on optimizing process parameters for milling, turning, drilling, and electrical discharge machining to control surface roughness and integrity. Recurring subjects include the development of cemented carbide and ceramic cutting tools, the application of minimum quantity lubrication, and the use of finite element and molecular dynamics simulations to model material removal mechanisms. The research specifically addresses the challenges of machining aerospace-grade alloys like Inconel 718 and TC4 titanium, as well as brittle ceramics like silicon carbide and gallium nitride, often employing hybrid techniques such as laser-assisted or ultrasonic-assisted processing to reduce damage and improve efficiency.
The community represents a significant share of research in tungsten (3.4%), titanium (1.6%), and aluminium (1.5%). It also contains the highest paper counts for carbon (5,090 papers) and titanium (4,693 papers).
The community comprises 34,649 papers, published primarily in The International Journal of Advanced Manufacturing Technology, International Journal of Refractory Metals and Hard Materials, and Procedia CIRP.
Recent work continues to explore the mechanisms of material removal in micro-drilling and nanomilling, with a focus on atomic-scale damage control in semiconductors and the application of machine learning to predict optimal cutting parameters for superalloys.
