Effect of Repeated Loads on the Low Temperature Fracture Behavior of Notched and Welded Plates [PDF]

, 1967
The influence of repeated loadings on the susceptibility of weldments to fracture in a brittle manner is studied for an ABS-Class C steel. The test members have consisted primarily of 12, 24 and 36 in.

Phosphorus Partition in an Industrial Basic Oxygen Furnace Process in Ukraine

steel research international, Volume 96, Issue 8, August 2025.
Phosphorus partition data from Ukrainian steel plants are analyzed, focusing on parameters like basicity, optical basicity, tapping temperature, and slag contents of FeO, MgO, and Al2O3. The analysis shows that phosphorus partition decreases with higher tapping temperatures and increases with optical basicity.

Medium-frequency electrical resistance sintering of oxidized C.P. iron powder [PDF]

, 2018
Commercially pure (C.P.) iron powders with a deliberate high degree of oxidation were consolidated by medium-frequency electrical resistance sintering (MF-ERS). This is a consolidation technique where pressure, and heat coming from a low-voltage and high-

Coupled Paleomagnetism and 40Ar/39Ar Dating of Latera Ignimbrites (Vulsini Volcanic District, Italy) Unravel Processes Associated to Piston‐Collapse Calderas

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Correlation of ignimbrite units at polygenic calderas is mandatory for the reconstruction of caldera‐forming events and proper identification of their eruption dynamics. However, ignimbrites erupted at different times from the same caldera can display similarities in composition and lithology that can hamper proper correlation of outcrops ...

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 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 ...

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.
