@article { , title = {Neutron diffraction residual strain measurements of molybdenum carbide-based solid oxide fuel cell anode layers with metal oxides on Hastelloy X.}, abstract = {Thermal spray deposition processes impart residual stress in layered Solid Oxide Fuel Cells (SOFC) materials and hence influence the durability and efficiency of the cell. The current study which is the first of its kind, reports results on using a neutron diffraction technique, to non-destructively evaluate the through thickness strain measurement in plasma sprayed (as-sprayed) anode layer coatings on Hastelloy\{reg\}X substrate. Through thickness neutron diffraction residual strain measurements has been done on three different anode coatings (Mo-Mo2C/Al2O3, Mo-Mo2C/ZrO2 and Mo-Mo2C/TiO2) using the vertical scan mode. The three anode coatings (developed through optimized process parameters) investigated had porosities as high as 20\%, with thicknesses between 200 \{aelig\}m to 300 \{aelig\}m deposited on 4.76 mm thick Hastelloy\{reg\}X substrate discs of 20 mm diameter. The results show that the through thickness residual strain in all three anodes was different for different crystallographic planes but was on average it was tensile. Other measurements includes X-ray diffraction, nanoindentation and SEM microscopy. As the anode layer microstructures are complex (includes bi-layer alternate phases), non-destructive characterisation of residual strain, e.g. using neutron diffraction, provides a useful measure of through thickness strain profile without altering the stress field in the SOFC electrode assembly.}, doi = {10.1007/s11340-017-0298-7}, eissn = {1741-2765}, issn = {0014-4851}, issue = {4}, journal = {Experimental mechanics}, note = {COMPLETED -- Now published 26/3/2018 LM -- Still not fully pub 26/2/2018, 26/1/2018, 21/12/2017 LM -- 5/12/2017, 22/9/2017, 21/8/2017, 24/7/2017 LM -- Upload as UPLOADED PENDING until VOR available for use 18/5/2017 LM -- Rec'd Springer Gold verification request for a very similar title; assumed it is the same article and so have changed details below accordingly; waiting for VoR to become available on Springer website, but can create record in advance if AAM received 16.05.2017 GB -- Contact confirms that this is almost at the stage of acceptance and that they will send us a copy as soon as available 10.05.2017 GB -- Requested update from contact 9/5/2017 LM -- Reply from Faisal that still under review 2/3/2017 LM -- Requested update 24/2/2017 LM -- Faisal reports that script still with reviewers (June) but will update us when he knows anything 3/11/2016 LM -- Resent update request 3/11/2016 LM -- Update requested from contact 1/9/2016 LM -- Info from Research outputs 26/4/2016 ADDITIONAL INFORMATION: Faisal, Nadimul Haque -- Panel B}, pages = {585-603}, publicationstatus = {Published}, publisher = {Springer}, url = {http://hdl.handle.net/10059/2314}, volume = {58}, keyword = {SOFC, Neutron scattering, Residual strain, Plasma spray, Nanoindentation}, year = {2018}, author = {Faisal, Nadimul Haque and Ahmed, Rehan and Prathuru, Anil Kumar and Katikaneni, Sai P. and Goosen, Mattheus F.A. and Zhang, Shu Yan} }
