The effect of grain size on the twin initiation stress in a TWIP steel
TL;DR: In this paper, the influence of grain size on the twinning stress of an Fe-15Mn-2Al-2Si-0.7C twinning induced plasticity (TWIP) steel was investigated.

Alloying effects in polycrystalline γ′ strengthened Co-Al-W base alloys
TL;DR: In this paper, a polycrystalline hot working ingot metallurgy processing route for γ/γ′ Co-Al-W superalloys has been developed, based on substitutions of Mo, V, Ti, Ta, Ni, Si, Fe and Cr.

High-resolution electron microscopy of dislocation ribbons in a CMSX-4 superalloy single crystal
TL;DR: In this paper, high-resolution scanning transmission electron microscopy (STEM) has been used to study the structure of dislocations in single crystal superalloy samples that have been subjected to conditions that favour the primary creep regime.

TL;DR: In this paper, it was shown that there exists significant compositional variation associated with superlattice intrinsic stacking faults created in the ordered γ′ precipitates following intermediate temperature deformation of two commercial superalloys.

Coarsening behaviour and interfacial structure of γ′ precipitates in Co-Al-W based superalloys
TL;DR: In this article, the effects of alloying on the coarsening behavior of the L12 ordered γ′ phase and the structure of the γ/γ′ interfaces in three Co-Al-W base superalloys aged at ∼90 °C below the respective solvus temperatures were discussed.
