TL;DR: A combination of experimental and modeling efforts reveals a substantial reduction of damage accumulation under prolonged irradiation in single-phase NiFe and NiCoCr alloys compared to elemental Ni, explained by reduced dislocation mobility, which leads to slower growth of large dislocation structures.

TL;DR: In this paper, the authors investigated the origin of the exceptional properties of NiCoCr alloy, which are related to the evolution of the deformation substructure with strain, interrupted tensile testing was conducted on the equiatomic NiCo-Cr single-phase solid solution alloy at both cryogenic and room temperatures at five different plastic strain levels of 1.5, 6.5%, 29, 50% and 70%.

TL;DR: In this article, a NiAl-Mo eutectic was directionally solidified to produce composites with well-aligned single-crystal Mo-alloy fibers embedded in NiAl matrix, and then the matrix was etched away to expose free-standing micropillars having different sizes (360-1400 nm) and different amounts of pre-strain (0-11%).

TL;DR: In this article, single-crystal micro-pillars of a molybdenum alloy were prepared by a new technique that involves chemically etching away the matrix of a directionally solidified NiAl-Mo eutectic.

TL;DR: An EXAFS analysis of Ni ion irradiated samples reveals that the degree of SRO in NiCoCr alloys is enhanced after irradiation, and this short-range order (SRO) may make an important contribution to the low values of the electrical and thermal conductivities of the Cr-alloyed solid solutions.
