Phase nucleation, coarsening and evolution pathways of a sputtered nanostructured Inconel 725 alloy during heat treatment
Ruqing Cao, Ikponmwosa J. Iyinbor, Andrea M. Hodge +1
Physical vapor deposition enables the fabrication of nanostructured superalloys with unique defect architectures, yet their phase evolution pathways can differ significantly from t…
Synergistic doping of the grain interior and grain boundary alters deformation mechanisms and enables extreme strength in nanocrystalline Ni-Cr-Y alloys
Yi Liu, Jason R. Trelewicz, Timothy J. Rupert
Solid solution addition and grain boundary segregation have been independently shown to enhance the strength of nanocrystalline alloys. In the present study, the interplay between…
A computational alloy design framework for the promotion of amorphous grain boundary complexions
Prince Sharma, Jaime Marian, Jason R. Trelewicz +1
Amorphous grain boundary complexions have been shown to be radiation tolerant interfaces that can also reduce grain boundary embrittlement, marking them as favorable microstructura…
Stress field modification near linear complexions increases the effective obstacle size and strengthening effect
Zhengyu Zhang, Daniel S. Gianola, Timothy J. Rupert
Linear complexions are stable defect states that form along dislocations and recent experiments have demonstrated strengthening effects exceeding classical precipitation hardening…
Fragmenting Diffusion Pathways Confers Extraordinary Radiation Resistance in Refractory Multicomponent Alloys
Bin Xing, Bijun Xie, Wanjuan Zou +11
The accumulation and growth of vacancy clusters under irradiation is a pivotal degradation mode for structural materials in extreme environments. Even tungsten undergoes rapid defe…
Irradiation-Driven Recrystallization in Fusion-Grade Tungsten: A Mesoscale, Microstructure-Aware Model
Jinxin Yu, Sicong He, Giacomo Po +3
Tungsten (W) is the leading candidate material for plasma-facing components in fusion reactors, yet its upper operational temperature is limited by premature grain growth and recry…
