Achieving Excellent Strength–Ductility in Nb‐Si Superalloys via Stable Bi‐Phases Structure and Nano‐Precipitation Behaviors

Rare Metals, EarlyView.
ABSTRACT Nb‐Si‐based superalloys are considered as the most potential candidate materials for nickel‐based superalloys due to the lower density and higher using temperature. Here, a type of stable Nbss/γNb5Si3 bi‐phases structure with a coherent interface has been successfully designed. Additionally, the Nbss and γNb5Si3 phases showcase the orientation

Surface structure, pore characteristics and mechanical response of aluminum foam processed by wire-EDM and milling

MATEC Web of Conferences, 2018
Material removal processes like milling, leave only a small process window to minimally distort the surface of Aluminum foams. Wire-EDM arises as a suitable alternative. Closed-cell aluminum foams were produced and processed at various conditions through

Study of Fine-Finish Wire EDM

Journal of The Japan Society of Electrical Machining Engineers, 2011
In this paper, methods of obtaining fine-finish surfaces in wire electrical discharge machining are discussed. Some countermeasures to reduce the stray capacitance of wire EDM, which restricts the surface roughness on an EDMed surface, are described. A surface roughness of 0.6[μm] Rz is obtained using a 0.1[μs] pulse width group type AC pulse generator.

A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

steel research international, EarlyView.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.
