Review of Flash Joule Heating for the Synthesis of Graphene and Other Functional Carbon Materials

Carbon Energy, EarlyView.
ABSTRACT Flash Joule heating (FJH), as a high‐efficiency and low‐energy consumption technology for advanced materials synthesis, has shown significant potential in the synthesis of graphene and other functional carbon materials. Based on the Joule effect, the solid carbon sources can be rapidly heated to ultra‐high temperatures (> 3000 K) through ...

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.
