Accumulative fold-forging (AFF) as a novel severe plastic deformation process to fabricate a high strength ultra-fine grained layered aluminum alloy structure
Khodabakhshi, Farzad; Gerlich, Adrian P. (Elsevier, 2018-02-01)A novel severe plastic deformation (SPD) process termed accumulative fold forging (AFF) is introduced to fabricate a homogenous ultra-fine grained (UFG) layered metal structure by repetitive folding and forging aluminum ... -
Depth-sensing thermal stability of accumulative fold-forged nanostructured materials
Khodabakhshi, Farzad; Gerlich, Adrian P.; Verma, D.; Nosko, Martin; Haghshenas, M. (Elsevier, 2021-04)Accumulative fold-forging (AFF) as a newly developed severe plastic deformation (SPD) process based on the repetitive fold-forging steps is implemented for the production of the layered UFG (~200 nm) AA8006 alloy and ... -
Effect of quality control parameter variations on the fatigue performance of aluminum friction stir welded joints
Guo, Shihui; Shah, Luqman; Ranjan, Rakesh; Walbridge, Scott; Gerlich, Adrian P. (Elsevier, 2019-01-01)This paper describes fatigue tests performed on 6061-T651 and 5083-H321 aluminum friction stir welded joints with dimensions and loading conditions typical for structural applications. Butt and lap joint details with various ... -
Effects of graphene nano-platelets (GNPs) on the microstructural characteristics and textural development of an Al-Mg alloy during friction-stir processing
Khodabakhshi, Farzad; Nosko, Martin; Gerlich, Adrian P. (Elsevier, 2018-02-15)The aim of this research is to characterize the unique microstructural features of Al-matrix nanocomposites reinforced by graphene nano-platelets (GNPs), fabricated by multi-pass friction-stir processing (FSP). During this ... -
Interfacial bonding mechanism in Al/coated steel dissimilar refill friction stir spot welds
Shen, Z.; Ding, Y.; Chen, J.; Amirkhiz, B. Shalchi; Wen, John Z.; Fu, L.; Gerlich, Adrian P. (Elsevier, 2019-06-01)Defect-free dissimilar Al/zinc coated steel and Al/AlSi coated steel welds were successfully fabricated by refill friction stir spot welding. However, Al alloy and uncoated steel could not be welded under the same weldin ... -
Interfacial bonding mechanisms between aluminum and titanium during cold gas spraying followed by friction-stir modification
Khodabakhshi, Farzad; Marzbanrad, Bahareh; Jahed, Hamid; Gerlich, Adrian P. (Elsevier, 2018-12-31)This paper closely evaluates the interfacial bonding mechanism between titanium particles deposited on an aluminum alloy substrate by cold gas spraying followed by friction-stir processing (FSP). After cold spraying and ...
