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.

Minimization of Porosity in E11018‐G Low‐Alloyed Steel Processed by Laser Powder Directed Energy Deposition

steel research international, EarlyView.
The processability of the E11018‐G by laser powder directed energy deposition (LP‐DED) is investigated. The effects of powder moisture, ambient humidity, and laser remelting on LP‐DED parts’ porosity are shown. A strong influence of the atomizing gas is observed.

Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

steel research international, EarlyView.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Modular and Vertically Integrated Microsupercapacitor Arrays Based on Laser‐Induced Graphene and Bimetallic Oxide Interfaces on Liquid Crystal Polymer Substrate

Small Structures, EarlyView.
Modular and flexible MSCs are fabricated through a fully integrated, laser‐assisted process that enables in‐situ synthesis of bimetallic nanodomains on LIG patterned LCP substrates. The multilayered architecture, formed via laser‐drilled vertical interconnects, supports compact energy modules with robust electrochemical performance, ensuring consistent

Cyclic Plastic Material Behavior of Novel Austenitic (C + N) Steel Additively Manufactured by PBF‐LB/M

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The newly introduced high manganese high strength (C + N) steel Printdur HSA was developed for the additive manufacturing process PBF‐LB/M. It consists of a fully austenitic grain structure. This study aims to evaluate the cyclic plastic material behavior of this (C + N) steel.
