Title: In-situ synchrotron X-ray diffraction study of dual-step strain variation in laser shock peened metallic glasses

Abstract

Atomic-structure evolution is significant in understanding the deformation mechanism of metallic glasses. Here, we firstly find a dual-step atomic strain variation in laser-shock-peened (LSPed) metallic glasses during compression tests by using in-situ synchrotron X-ray diffraction. Under low compressive load, LSP-deformed zone’s atomic-structure shows low Young’s Modulus (E); with load increase, atomic-structure are re-hardened, showing high E. An atomic deformation mechanism is proposed by using flow unit model, that LSP could induce interconnected flow units and 2 homogenize the atomic-structure. Furthermore, these interconnected flow units are metastable and start to annihilate during compressive loading, causing the dual-step atomic strain variation.

Unveiling the origins of work-hardening enhancement and mechanical instability in laser shock peened titanium

Journal Article Li, Runguang ; Wang, Youkang ; Xu, Ning ; ... - Acta Materialia

Laser shock-peening (LSP) produces complex gradients in microstructures and residual stresses, which enables fabrication of metallic engineering components with superior mechanical properties. In this work, we use non-destructive and spatially resolved high-energy X-ray diffraction (HE-XRD) to investigate the influences of LSP on microstructure, surface topography, and residual stress for high purity titanium plates. LSP is found to produce large compressive in-plane residual stresses near the peened surface which monotonically decay to zero about 2.5 mm below the surface. These properties were also tracked during in-situ tensile loading, allowing stress partitioning and work-hardening rates to be measured as a function ofmore »« less

Intergranular stress study of TC11 titanium alloy after laser shock peening by synchrotron-based high-energy X-ray diffraction

Journal Article Su, R. ; Li, L. ; Wang, Y. D. ; ... - AIP Advances

The distribution of residual lattice strain as a function of depth were carefully investigated by synchrotron-based high energy X-ray diffraction (HEXRD) in TC11 titanium alloy after laser shock peening (LSP). The results presented big compressive residual lattice strains at surface and subsurface, then tensile residual lattice strains in deeper region, and finally close to zero lattice strains in further deep interior with no plastic deformation thereafter. These evolutions in residual lattice strains were attributed to the balance of direct load effect from laser shock wave and the derivative restriction force effect from surrounding material. Significant intergranular stress was evidenced inmore »« less

Localized plastic deformation and hardening in laser shock peened Inconel alloy 718SPF

Journal Article Gill, Amrinder S. ; Telang, Abhishek ; Ye, Chang ; ... - Materials Characterization

Highlights: • The plastic strain in LSP-treated Inconel 718 alloy was characterized using EBSD. • LSP increases the low angle misorientations in the near-surface region, indicating the extend of plastic strain. • The near-surface plastic strain leads to an increase in local hardness and yield stress. - Abstract: Localized plastic deformation and hardening was studied in laser shock peened (LSP) Inconel 718 SPF (Super plastic forming), a fine grained Ni-Base superalloy, using electron backscatter diffraction (EBSD), nanoindentation, and micro pillar compression testing. 718SPF samples were LSP-treated with two different laser power densities. After LSP, the plastic deformation is manifested asmore »« less

Evolution of residual stress, free volume, and hardness in the laser shock peened Ti-based metallic glass

Journal Article Wang, Liang ; Wang, Lu ; Nie, Zhihua ; ... - Materials & Design

Laser shock peening (LSP) with different cycles was performed on the Ti-based bulk metallic glasses (BMGs). The sub-surface residual stress of the LSPed specimens was measured by high-energy X-ray diffraction (HEXRD) and the near-surface residual stress was measured by scanning electron microscope/focused ion beam (SEM/FIB) instrument. The sub-surface residual stress in the LSP impact direction (about-170MPa) is much lower than that perpendicular to the impact direction (about -350 MPa), exhibiting anisotropy. The depth of the compressive stress zone increases from 400 mu m to 500 mu m with increasing LSP cycles. The highest near-surface residual stress is about -750 MPa.more »« less

Quantification of room temperature strengthening of laser shock peened Ni-based superalloy using synchrotron microdiffraction

Journal Article Zhou, Guangni ; Zhang, Yubin ; Pantleon, Wolfgang ; ... - Materials & Design

Laser shock peening (LSP), a surface modification technique, is promising to enhance the strength and wear resistance for Ni-based superalloys. To understand the strengthening mechanism in a laser shock peened Ni-based superalloy DZ417G, we utilize synchrotron poly- and monochromatic X-ray microdiffraction, as well as electron microscopy and microhardness to quantify the local microstructures and mechanical properties at various depths. In the 1.2-mm-deep hardened layer, the microhardness increases monotonically by ~50% from the unaffected interior to the surface. Quantitative microdiffraction analysis shows that large amounts of dislocations are introduced by LSP. High densities of 7.1 × 10¹⁵ m^-2 and 11.8 ×more »« less
