The Wrocław–Szczytniki flanged axe from Koperniki

open access: yesArcheologické Rozhledy, 2017
This work is a contribution to archaeometallurgical studies on the Únětice axes in Poland. The research was initiated by a single find of the Wrocław–Szczytniki flanged axe recovered from the village of Koperniki (Lower Silesia, Poland).

Reinterpretation of Report of Tetrataenite in Bulk Alloy Castings

open access: yesAdvanced Science, Volume 12, Issue 4, January 27, 2025.
After publication, the authors of Advanced Science 10 (2022) 2204315 identified a potential misinterpretation of their data. This comment accompanies retraction of that paper, and reports further characterization of cast Fe‐Ni‐P‐(C) alloys using X‐ray diffraction, electron diffraction and magnetometry.

Correlation between microstructural deformation mechanisms and acoustic parameters on a cold-rolled Cu30Zn brass [PDF]

open access: yesarXiv, 2023
The relationship between acoustic parameters and the microstructure of a Cu30Zn brass plate subjected to plastic deformation was evaluated. The plate, previously annealed at 550 {\deg}C for 30 minutes, was cold rolled to reductions in the 10-70\% range.

Effect of Heat Treatment on Performance of 2205 Base Equipment and Pipes

open access: yesEngineering Reports, Volume 7, Issue 1, January 2025.
The heat treatment process seriously affects the impact toughness and CPT of 2205 duplex stainless steel. The operating temperature should be controlled to effectively reduce the point corrosion sensitivity of the material, according to the heat treatment temperature.

Two channel heat conduction in the superconducting state of the as-cast V$_{1-x}$Zr$_x$ alloys [PDF]

open access: yes, 2019
We present here the temperature dependence of heat capacity ($C$($T$)) and thermal conductivity ($\kappa$($T$)) in the superconducting state as well as in the normal state of as-cast V$_{1-x}$Zr$_x$ alloys. Distinct jumps in the $C$($T$) of the alloys indicate the presence of three superconducting phases with transition temperatures $T_{C1}$ = 5.4~K ...

Investigation on Applicability of Lime as Desulfurization Agent for Molten Cast Iron

open access: yessteel research international, Volume 96, Issue 1, January 2025.
Despite containing higher silicon concentration than pig iron, lime‐based desulfurization is proven effective in achieving low sulfur content in cast iron. Its success depends on the interplay between dissolved oxygen and the establishment of liquid slag.

Experimental Determination of a Strain State in a Bulk Forming of a Low Carbon Steel

open access: yesMedžiagotyra
An experimental metallographic method for determining strain distribution in a cold formed workpiece is presented in this paper. The method, based on the dependence of recrystallized grain size on prior deformation, was applied to a bulk formed element ...
