Electro-slag-Welding of Cr-Mo Steels

Journal of the Japan Welding Society, 1964
Seeing the macro-structure of electro-slag welded Cr-Mo steels, its grain size is finer as compared with ASTM A 302 B. This is because the plate thickness of Cr-Mo steel is thinner and its cooling velocity is faster than ASTM A 302 B. grain growth of deposit-metal which is shortcoming of electro-slag welding becomes more remarkably in proportion to ...

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 ...

Numerical and Experimental Study of High‐Speed Laser Cutting of Copper Current Collectors: Process Optimization for Quality Assessment

Advanced Materials Technologies, Volume 10, Issue 14, July 22, 2025.
This study employs a CFD model to simulate laser cutting of copper current collectors used for Li‐Ion battery production. This model predicts cut edge quality by assessing the influence of power, scanner speed, and foil thickness. Defects are classified and an optimal working area is found.

Effect of nonmetallic inclusions on steel welds metal hot cracking

Metalurgija, 2014
Intercrystally distributed nonmetallic inclusions greatly increase weld susceptibility to hot cracking. Oxide and sulphide inclusions are the result of contaminated base material or its highly oxidised surfaces and they can be a consequence of ...

Metallurgy of armour exhibited at the Palace Armoury, Valletta, Malta [PDF]

, 2004
The metallurgy of ten armour pieces from the Palace Armoury Collection in Malta was examined. Results showed that out of ten artefacts examined, six were produced in low carbon steel, one from a high carbon steel and three were made from wrought iron ...

A comparison of methods to assess the resistance of reinforcing steel against chloride‐induced corrosion in concrete: Particular consideration of 12% chromium steel

Materials and Corrosion, Volume 76, Issue 7, Page 1041-1060, July 2025.
Several methods to measure the critical chloride content Ccrit of steel in concrete are compared on the basis of 12% chromium steel and carbon steel. The resulting Ccrit depends on the method used. The reasons for this and the corresponding influencing parameters are discussed in this article.

Low temperature vaporisation of Cr from fluoride flux reacted at 1350 °C with Al–Cr–Fe powder: Thermochemical analysis of gas phase reactions and nano-strand formation

Journal of Materials Research and Technology
The submerged arc welding (SAW) process is complex because multi-phase reactions occur simultaneously across a large temperature interval from 2500 °C in the arc cavity, down to the weld pool liquidus temperare at the slag-weld pool interface.

Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review

cMat, Volume 2, Issue 2, June 2025.
ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

Waste-based consumable for hardfacing by welding: a look from the Circular Economy

Dyna
In the present work, the obtaining of a consumable for the restore parts by welding from the perspective of the circular economy is addressed, using industrial solid residuals (slag from steel production, graphite from fragments of electrodes of arc ...
