A Perspective on Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed Stainless Steels

Advanced Engineering Materials, Volume 27, Issue 14, July 2025.
This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...

A Novel Approach on Rapid Alloy Development of Tool Steels for Laser Powder Bed Fusion by In Situ Alloying

Advanced Engineering Materials, Volume 27, Issue 14, July 2025.
A novel approach for alloy development in laser powder bed fusion is introduced. Instead of producing massive samples of one composition at a time, prepressed powder bed samples produced from powder mixtures are processed. Guidelines for the selection of precursor powders are developed.

Industrial Policy and Domestic Value‐Added in Production and Exports: The Chinese Experience

The World Economy, Volume 48, Issue 7, Page 1630-1653, July 2025.
ABSTRACT This paper studies the role of China's industrial policy in the evolving share of domestic value added (DVA) in its production and exports. We propose a method to quantify the DVA share in exports by extending. With national input–output tables and trade statistics from 2007 to 2020, we see a strong increase of the DVA share in exports and a ...

Critical Factors Governing the Frictional Coefficient in Mg Alloys—Learn From Machine Learning

Engineering Reports, Volume 7, Issue 5, May 2025.
Machine learning models were successfully used to predict the friction coefficient of Mg alloys based on composition, processing, mechanical properties, and tribological parameters. Normal load, elastic modulus, and Zn content are the most important factors in governing the friction coefficient in Mg alloys. ABSTRACT Data‐driven methods are emerging as

Sodium Oxide-Fluxed Aluminothermic Reduction of Manganese Ore with Synergistic Effects of C and Si Reductants: SEM Study and Phase Stability Calculations

Reactions
Aluminothermic reduction is an alternative processing route for the circular economy because Al is produced electrochemically in the Hall–Héroult process with minimal CO2 emissions if the electricity input is sourced from non-fossil fuel energy sources ...

Degradation Behavior and Mechanical Properties of Porous Biodegradable FeMnC Alloys Produced by Powder Metallurgy for Biomedical Applications

Advanced Engineering Materials, Volume 27, Issue 4, February 2025.
Biodegradable implants are transforming medicine by removing the need for secondary surgeries for implant removal. This study investigates FeMnC alloys, produced via pressing and sintering water‐atomized prealloyed powder, to evaluate how compaction pressures influence mechanical strength and degradation through porosity.

The structure and properties of a multilayer metal deposited by electrode flux-cored wires with a core of ferroalloy powders and granular hard alloy materials

Metaloznavstvo ta obrobka metalìv
Comparative studies of the possibility of using granulated hard alloy powders as a charge of flux-cored wires for electric arc surfacing have been carried out. In the studies, granulated powder of the PG-R6M5 brand with a fraction of 50...300 μm was used.
