Criticality of porosity defects on the fatigue performance of wire + arc additive manufactured titanium alloy

Biswal, Romali; Zhang, Xiang; Syed, Abdul Khadar; Awd, Mustafa; Ding, Jialuo; Walther, Frank; Williams, Stewart W. (Elsevier, 2019-01-28)

This study was aimed at investigating the effect of internal porosity on the fatigue strength of wire + arc additive manufactured titanium alloy (WAAM Ti-6Al-4V). Unlike similar titanium alloys built by the powder bed ...
Effect of deposition strategies on fatigue crack growth behaviour of wire+ arc additive manufactured titanium alloy Ti-6Al-4V

Syed, Abdul Khadar; Zhang, Xiang; Davis, Alec E.; Kennedy, Jacob R.; Martina, Filomeno; Ding, Jialuo; Williams, Stewart; Prangnell, Philip B. (Elsevier, 2021-04-03)

The influence of three deposition strategies on the fatigue crack growth behaviour of Wire + Arc Additive Manufactured (WAAM) Ti–6Al–4V has been investigated in the as-built condition. Test samples were prepared using ...
Effect of impact damage on fatigue performance of structures reinforced with GLARE bonded crack retarders

Syed, Abdul Khadar; Fitzpatrick, Michael E.; James E. Moffatt; Doucet, Jeremy; Durazo-Cardenas, Isidro (Elsevier, 2015-06-19)

Fibre-Metal Laminates (FML) such as GLARE are of interest as bonded crack retarders (BCR) to improve the fatigue performance of aircraft structures. The degradation of the performance of the crack retarder in service if ...
Fatigue crack growth behavior in an aluminum alloy Al–Mg–0.3Sc produced by wire based directed energy deposition process

Ye, Jin; Syed, Abdul Khadar; Zhang, Xiang; Eimer, Eloise; Williams, Stewart (Wiley, 2023-07-29)

Additive manufacturing (AM) of Al–Mg–Sc alloys has received considerable interest from the aerospace industry owing to their high specific strength and suitability for AM processes. This study has investigated the fatigue ...
Fatigue crack growth in additive manufactured titanium: residual stress control and life evaluation method development

Zhang, Xiang; Martina, Filomeno; Syed, Abdul Khadar; Wang, Xueyuan; Ding, Jialuo; Williams, Stewart W. (VTT Information Service, 2017-06-09)

This paper presents fatigue crack growth behaviour in titanium alloy Ti-6Al-4V built by the Wire + Arc Additive Manufacture (WAAM®) process. Process induced residual stress and stress relief by cold working were measured ...
High cycle fatigue and fatigue crack growth rate in additive manufactured titanium alloys

Zhang, Xiang; Syed, Abdul Khadar; Biswal, Romali; Martina, Filomeno; Ding, Jialuo; Williams, Stewart W. (Springer, 2019-07-03)

The Wire + Arc Additive Manufacture (WAAM) process can produce large metal parts in the metre scale, at much higher deposition rate and more efficient material usage compared to the powder bed fusion additive manufacturing ...
Influence of deposition strategies on tensile and fatigue properties in a wire + arc additive manufactured Ti-6Al-4V

Syed, Abdul Khadar; Zhang, Xiang; Caballero, Armando; Shamir, Muhammad; Williams, Stewart (Elsevier, 2021-04-15)

This paper investigates the influence of two different deposition strategies, oscillation and parallel pass, on the tensile and high cycle fatigue properties of a wire + arc additive manufactured Ti-6Al-4V alloy in the ...
The role of microstructure and local crystallographic orientation near porosity defects on the high cycle fatigue life of an additive manufactured Ti-6Al-4V

Shamir, Muhammad; Syed, Abdul Khadar; Janik, Vit; Biswal, Romali; Zhang, Xiang (Elsevier, 2020-08-21)

Titanium alloys such as Ti-6Al-4V built by most of the additive manufacturing processes are known to contain process induced defects, non-conventional microstructure and strong crystallographic texture; all of which can ...
Strain controlled fatigue behaviour of a wire + arc additive manufactured Ti-6Al-4V

Syed, Abdul Khadar; Plaskitt, Rob; Hill, Michelle; Pinter, Zsolt; Ding, Jialuo; Zboray, Robert; Williams, Stewart; Zhang, Xiang (Elsevier, 2023-02-24)

This paper presents the cyclic deformation behaviour and fatigue properties of a wire + arc additive manufactured Ti-6Al-4V alloy in the as built condition under strain-controlled test condition. Higher local energy input ...
