Linear complexions enable unprecedented ductility retention in neutron irradiated ferritic steel Open
Herein, the operando formation of Si-enriched linear complexions during neutron enables Grade 91 ferritic steel to overcome the strength–ductility tradeoff, one of the most critical life-limiting challenges facing nuclear structural alloys…

Irradiation-assisted pseudoelasticity in 316L stainless steel through dislocation loop-controlled martensitic phase transformations Open
We present pseudoelasticity activated by neutron irradiation in 316L austenitic stainless steel. Wrought and powder metallurgy with hot isostatic pressing (PM-HIP) specimens are irradiated to ∼4 displacements per atom at ∼400°C, then nanoi…

Phase Transitions of Cu and Fe at Multiscales in an Additively Manufactured Cu–Fe Alloy under High-Pressure Open
A state of the art, custom-built direct-metal deposition (DMD)-based additive manufacturing (AM) system at the University of Michigan was used to manufacture 50Cu–50Fe alloy with tailored properties for use in high strain/deformation envir…

Metal-ion-controlled growth and nanoindentation response of 3D, bicontinuous Cu–Fe thin films Open
Bicontinuous, nanocomposite thin film morphologies depend largely on the deposition conditions applied during physical vapor deposition. With the introduction of high-power impulse magnetron sputtering (HiPIMS), the range of potential morp…

Effect of tilt and twist angles on the cleavage crack propagation Open
We report the mechanism of cleavage crack deviation at grain boundaries. A fracture mechanics based model has been developed to combine the effect of tilt and twist angles between cleavage planes on the reduction in normalized energy relea…

The role of crystallographic orientation of martensitic variants on cleavage crack propagation Open
Cleavage crack propagation has been investigated in a low-carbon lath-martensitic steel using electron back-scattered diffraction technique. The ability of different martensitic boundaries within prior-austenite grain, such as sub-block, b…

Development of Si-Mn Alloyed Spring Steels Suitable for Elastic Rail Clip (ERC) Application Open
Spring steels are used for making leaf springs for automotives, elastic rail clips (ERC) for railways, and coil springs for various applications. No residual plastic deformation is permissible even under heavy static or cyclic loads and sp…
