Title: Exploring novel deformation mechanisms in aluminum–copper alloys using in situ 4D nanomechanical testing

Abstract

Even after nearly a century of extensive use of aluminum alloys in structural applications, our understanding of such precipitation-strengthened materials is far from complete. With the advent of next generation advanced characterization techniques, our ability to probe materials in unique ways and at different length scales has established a new paradigm for devising new pathways to alloy design by engineering materials and tailoring specific properties at the nanoscale. Here, we perform in situ nanomechanical testing in conjunction with synchrotron -based hard X-ray nanotomography to capture initiation and evolution of damage in 3D in Al-Cu alloys. Precipitates in these alloys are seen to exhibit unprecedented localized deformation in compression, which is attributed to novel observations of kinking in these brittle second-phase particles, accompanied with the generation of a fine polycrystalline texture in the adjacent matrix. We observe a size-dependent transition in precipitate deformation behavior that has been thoroughly investigated using a comprehensive correlative approach.

Probing Novel Microstructural Evolution Mechanisms in Aluminum Alloys Using 4D Nanoscale Characterization

Journal Article Kaira, C. Shashank ; De Andrade, V. ; Singh, Sudhanshu S. ; ... - Advanced Materials

Dispersions of nanoscale precipitates in metallic alloys have been known to play a key role in strengthening, by increasing their strain hardenability and providing resistance to deformation. Although these phenomena have been extensively investigated in the last century, the traditional approaches employed in the past have not rendered an authoritative microstructural understanding in such materials. The effect of the precipitates’ inherent complex morphology and their 3D spatial distribution on evolution and deformation behavior have often been precluded. This study reports, for the first time, implementation of synchrotron-based hard X-ray nanotomography in Al–Cu alloys to measure kinetics of different nanoscale phasesmore »« less

Nanomechanical Scratching Induced Local Shear Deformation and Microstructural Evolution in Single Crystalline Copper

Journal Article Efe, Mert ; Gwalani, Bharat ; Tao, Jinhui ; ... - Applied Surface Science

Shear deformation at the nanoscale has practical applications due to the ability of shear strains to cause significant changes in the microstructures and textures of the deforming materials, as well as for material removal processes at this scale. In this study, we demonstrate nano-scratching with atomic force microscopy (AFM) as a tool to impose large shear strains on nanoscale material volumes of a single-crystal copper workpiece. Nano-scratching, with the process parameters and AFM tip geometry used in this study, resulted in material removal through the cutting mode. This mode enabled the use of stress and strain models, developed for themore »« less

Deformation of nanotubes in peeling contact with flat substrate: An in situ electron microscopy nanomechanical study

Journal Article Chen, Xiaoming ; Zheng, Meng ; Wei, Qing ; ... - Journal of Applied Physics

Peeling of one-dimensional (1D) nanostructures from flat substrates is an essential technique in studying their adhesion properties. The mechanical deformation of the nanostructure in the peeling experiment is critical to the understanding of the peeling process and the interpretation of the peeling measurements, but it is challenging to measure directly and quantitatively at the nanoscale. Here, we investigate the peeling deformation of a bundled carbon nanotube (CNT) fiber by using an in situ scanning electron microscopy nanomechanical peeling technique. A pre-calibrated atomic force microscopy cantilever is utilized as the peeling force sensor, and its back surface acts as the peelingmore »« less

Fatigue and Creep-Fatigue Deformation of an Ultra-Fine Precipitate Strengthened Advanced Austenitic Alloy

Journal Article Carroll, M C ; Carroll, L J - Materials Science and Engineering A

An advanced austenitic alloy, HT-UPS (high-temperature ultrafine-precipitation-strengthened), has been identified as an ideal candidate material for the structural components of fast reactors and energy-conversion systems. HT-UPS alloys demonstrate improved creep resistance relative to 316 stainless steel (SS) through additions of Ti and Nb, which precipitate to form a widespread dispersion of stable nanoscale metallic carbide (MC) particles in the austenitic matrix. The low-cycle fatigue and creep-fatigue behavior of an HT-UPS alloy have been investigated at 650 °C and a 1.0% total strain, with an R-ratio of -1 and hold times at peak tensile strain as long as 150 min.

Shear-based deformation processing of age-hardened aluminum alloy for single-step sheet production

Journal Article Bai, Xiaolong ; Kustas, Andrew ; Mann, James B. ; ... - Journal of Manufacturing Science and Engineering

Shear-based deformation processing by hybrid cutting-extrusion and free machining are used to make continuous strip, of thickness up to one millimeter, from low-workability AA6013-T6 in a single deformation step. The intense shear can impose effective strains as large as 2 in the strip without pre-heating of the workpiece. The creation of strip in a single step is facilitated by three factors inherent to the cutting deformation zone: highly confined shear deformation, in situ plastic deformation-induced heating and high hydrostatic pressure. The hybrid cutting-extrusion, which employs a second die located across from the primary cutting tool to constrain the chip geometry,more »« less
