Abstract A grand challenge in material science is to understand the correlation between intrinsic properties and defect dynamics. Radiation tolerant materials are great demand for safe operation advancement of nuclear aerospace systems. Unlike traditional approaches that rely on microstructural nanoscale features mitigate radiation damage, this study demonstrates enhancement tolerance with suppression void formation by two orders magnitude at elevated temperatures equiatomic single-phase...
A grand challenge in materials research is to understand complex electronic correlation and non-equilibrium atomic interactions, how such intrinsic properties dynamic processes affect energy transfer defect evolution irradiated materials. Here we report that chemical disorder, with an increasing number of principal elements and/or altered concentrations specific elements, single-phase concentrated solid solution alloys can lead substantial reduction electron mean free path orders magnitude...
Recently a new class of metal alloys, single-phase multicomponent composition at roughly equal atomic concentrations (``equiatomic''), have been shown to exhibit promising mechanical, magnetic, and corrosion resistance properties, in particular, high temperatures. These features make them potential candidates for components next-generation nuclear reactors other high-radiation environments that will involve temperatures combined with corrosive extreme radiation exposure. In spite wide range...
Multielement solid solution alloys are intrinsically disordered on the atomic scale, and many of their advanced properties originate from local structural characteristics. The structure a NiCoCr alloy is measured with x-ray or neutron total scattering extended absorption fine (EXAFS) techniques. pair distribution function analysis does not exhibit an observable distortion. However, EXAFS suggests that Cr atoms favorably bonded Ni Co in alloys. This short-range order (SRO) may make important...
A group of single-phase concentrated solid-solution alloys (SP-CSAs), including NiFe, NiCoFe, NiCoFeCr, as well a high entropy alloy NiCoFeCrMn, was irradiated with 3 MeV Ni2+ ions at 773 K to fluence 5 × 1016 ions/cm2 for the study radiation response increasing compositional complexity. Advanced transmission electron microscopy (TEM) energy loss spectroscopy (EELS) used characterize dislocation loop distribution and radiation-induced segregation (RIS) on defect clusters in SP-CSAs. The...
Equiatomic alloys (e.g. high entropy alloys) have recently attracted considerable interest due to their exceptional properties, which might be closely related extreme disorder induced by the chemical complexity. In order understand effects of complexity on fundamental physical a family (eight) Ni-based, face-center-cubic (FCC), equiatomic alloys, extending from elemental Ni quinary has been synthesized, and electrical, thermal, magnetic properties are systematically investigated in range...
The computer code, Stopping and Range of Ions in Matter (SRIM), is widely used to describe energetic processes ion-solid interactions; its predictive power relies on the accuracy energy loss/transfer collision being considered. While SRIM code commonly applied radiation effects research predict damage production semiconductor industry estimate ion range dopant concentration profiles, two challenges exist that affect use: (1) inconsistency estimations atomic displacements between full-cascade...
Energetic ions have been widely used to evaluate the irradiation tolerance of structural materials for nuclear power applications and modify material properties. It is important understand defect production, annihilation migration mechanisms during after collision cascades. In this study, single crystalline pure nickel metal single-phase concentrated solid solution alloys 50%Ni50%Co (NiCo) 50%Ni50%Fe (NiFe) without apparent preexisting sinks were employed study dynamics under ion...
Using ab initio calculations and special quasirandom structures, we have characterized the distribution of defect formation energy migration barrier in Ni-based solid-solution alloys: Ni_{0.5}Co_{0.5}, Ni_{0.5}Fe_{0.5}, Ni_{0.8}Fe_{0.2} Ni_{0.8}Cr_{0.2}. As energies depend sensitively on elemental chemical potential, developed a computationally efficient method for determining it which takes into account global composition local short-range order. We find that Fe has biggest alloy effects Ni...
Although giant unilamellar vesicles (GUVs) have been extensively studied as synthetic cell-like microcompartments, their applicability cytomimetic models is severely compromised by low levels of membrane permeability, encapsulation efficiencies, and high physicochemical instability. Here, we develop an integrated model comprising a macromolecularly crowded interior with sequestration efficiency enclosed within phospholipid that permeable to molecules below molecular weight cutoff ca. 4 kDa....
