Atomic Scale Mechanisms of Multimode Oxide Growth on Nickel-Chromium Alloy: Direct in Situ Observation of the Initial Oxide Nucleation and Growth
(2021)The initial growth mode of oxide on alloy plays a decisive role in the development of protective oxide scales on metals and alloys, which is critical for their functionality for high temperature applications. However, the ... -
Corrosion damage evolution of the aircraft aluminum alloy 2024 T3
(2016)Purpose - The purpose of this paper is to quantify the corrosion damage evolution that has occurred on the aircraft aluminum alloy 2024 after the exposure to Exfoliation Corrosion Test (EXCO) solution. Moreover, the effect ... -
Corrosion of exposed rebars, associated mechanical degradation and correlation with accelerated corrosion tests
(2011)In a large number of steel reinforced concrete buildings in Greece, spalling of the cement has left the steel reinforcement (rebars) exposed to the atmosphere. This has led to corrosion of the exposed rebars, especially ... -
Effect of prior deformation and heat treatment on the corrosion-induced hydrogen trapping in aluminium alloy 2024
(2014)The nature of the corrosion-induced hydrogen trapping in Al-alloy 2024-T351 was studied by thermal desorption spectroscopy. The microstructure was altered by solution treatment and plastic deformation, prior to corrosion. ... -
An experimental approach for estimating the effect of heat affected zone (HAZ) microstructural gradient on fatigue crack growth rate in aluminum alloy FSW
(2017)The microstructural gradient of the heat affected zone (HAZ) in aluminum alloy FSW has been simulated experimentally by subjecting the parent alloy to a controlled aging process. The purpose of the simulation is to estimate ... -
Failure analysis of an aluminum extrusion aircraft wing component
(2016)Purpose - The purpose of this paper is to deal with the failure analysis of a fractured spar stiffener, extruded from 7075-T6 aluminum alloy, which was found in the central wing, trailing edge structure of a military ... -
Fatigue crack growth assessment of corroded aluminum alloys
(2009)The fatigue crack growth behaviour of pre-corroded aluminum alloy has been investigated analytically. For this purpose the fatigue crack growth LTSM-F model has been implemented and upgraded to account for the local material ... -
Fatigue crack growth of aircraft aluminum alloys
(2008)The microstructural characteristics and the influence of existing corrosion on fatigue crack growth in 2024 T351 aircraft aluminium alloy are investigated. Examined is the elongated grain morphology due to the rolling ... -
Fatigue failure investigation of pre-corroded and laser-welded Al-Cu-Mg-Ag Alloy with different temper condition
(2010)The fatigue failure mechanisms of pre-corroded, laser beam welded Al-Cu-Mg-Ag alloy in different temper conditions (T3,T8) have been investigated. Aging influences the corrosion behavior of laser welds. In the T3 temper, ... -
Fatigue performance of pre-corroded 6xxx aluminum alloy laser beam welds with dissimilar heat treatment
(2014)The role of existing corrosion damage on the fatigue performance of 6156 AA laser beam welds in T3 state, with additional post weld heat treatment T8, has been assessed. The welds were subjected to salt fog environment for ... -
Influence of FRP confinement on bond behavior of corroded steel reinforcement
(2011)This study investigates the bond behavior of corroded reinforcing steel confined with carbon fiber reinforced polymer (CFRP). Corrosion of steel reinforcement in reinforced concrete structural elements could pose a significant ... -
Influence of surface topography on corrosion of stainless steel AISI 304 turned surfaces with different cutting conditions
(2007)In this study, the correlation between corrosion behaviour and formations, and topographic characteristics of machined surfaces of stainless steel AISI 304 is investigated. Face turning was performed for combinations of ... -
Investigation on the protective role of local AL cladding against corrosion damage and hydrogen embrittlement of 2024 aluminum alloy specimens
(2004)The present investigation aims to inquire whether Al cladding of 2024 aluminum alloy specimens could provide, additionally to the expected protection against corrosion damage, also a protection against the corrosion induced ...
