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.

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

steel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Numerical Modeling Of GMAW ARC [PDF]

, 2007
A comprehensive model has been developed to simulate the transient, coupled transport phenomena occurring during a gas metal arc welding process. This includes the arc plasma; melting of the electrode; droplet formation, detachment, transfer, and impingement onto the workpiece; and weld pool fluid flow and dynamics.
