Shape memory effect and pseudoelasticity in Fe-Mn-based alloys
(Springer, 2016-12-16)
Several Fe-based alloys are being considered as potential candidates for applications which require shape-memory behavior or superelastic properties. The possibility of using fabrication methods which are well known in the ...
Corrosion Resistance of Aluminum-Copper Alloys with Different Grain Structures
(Springer, 2020-11)
Electrochemical studies and microstructure analysis of directionally solidified hypoeutectic and eutectic aluminum-copper alloys were performed. Optical and scanning electron microscopy studies of corroded specimens with ...
Effects of thermo-mechanical process on phase transitions, hydrogen solubility and corrosion of Ta-modified Zr-1Nb alloys
(Elsevier, 2021-09)
The feasibility of using Ta as a minor alloying element in Zr-1Nb alloys is addressed in terms of phase stability and resistance to corrosion of the microstructure obtained with the following two thermomechanical processes ...
Kinetics of isothermal decomposition in polycrystalline β CuAlBe alloys
(Elsevier, 2010-01)
The kinetics of the microstructural evolution of the metastable β phase during isothermal aging in a Cu-22.60Al-3.26Be (at%) polycrystalline shape memory alloy has been studied by electrical resistivity measurements and ...
Crevice corrosion kinetics of nickel alloys bearing chromium and molybdenum
(Pergamon-Elsevier Science Ltd, 2012-08)
The crevice corrosion kinetics of alloys C-22, C-22HS and HYBRID-BC1 was studied in several chloride solutions at 90°C. The crevice corrosion resistance of the alloys increased with PREN (Pitting Resistance Equivalent ...
Aluminium AA2024 T351 aeronautical alloy: Part 1. Microbial influenced corrosion analysis
(Elsevier Science Sa, 2008-01)
The aim of this paper was to correlate the elemental distribution of alloying elements with the MIC attack morphology of the AA2024 T351 alloy by the fungus Hormoconis resinae. Anodic polarisation was applied up to the Ep ...
Effect of Ti additions on phase transitions, lattice misfit, coarsening, and hardening mechanisms in a Fe2AlV-strengthened ferritic alloy
(Elsevier Science SA, 2019-10)
Ferritic Fe-Al-V alloys strengthened with L21-Fe2AlV precipitates are candidate materials to meet the steam temperature/pressure requirements of super- or ultra-supercritical thermal power plants. Precipitate features, ...
Influence of alloy element distributions on austempered ductile irons
(Maney Publishing, 2018-11)
The influence of alloy element distributions on austempered ductile iron microstructure and austempering treatment was analysed by a cellular automaton model that considers the ausferritic and martensitic transformations. ...
Composition effects on the fcc-hcp martensitic transformation and on the magnetic ordering of the fcc structure in Fe-Mn-Cr alloys
(Elsevier Ltd, 2017-02-15)
This paper presents an experimental study on the fcc/hcp martensitic transformation temperatures (MTTs) and Néel temperatures (TN) of the fcc phase of Fe-Mn-Cr alloys. A wide range of chemical compositions (13.7 < Mn < 27.5 wt.% ...
Significant hardness enhancement in an Al–Cu–Mg alloy with high Cu:Mg ratio by microalloying with Si and Ge
(Elsevier, 2018-12)
The evolution of hardness in an Al-Cu-Mg based alloy with high Cu:Mg ratio (= 2, at. %) microalloyed with Si and Ge was studied during artificial ageing treatment performed at 190 °C. The results were compared to those ...
