A numerical analysis of texture data was conducted to identify the type of Ni grain boundaries, which control grain growth and texture transformation.
We also discuss the grain boundary transformations and migrations that occur upon adding or removing carbon atoms at the grain boundaries for all of our investigated types of grain boundaries.
In the Σ = 3(2 1 1) grain boundary, the transformation is accompanied by a relative tangential translation of the grains.
Effects of the laser operating parameters on microstructures, in terms of porosity formation, crystallisation, phase transformation, grain growth, microstrain and residual stress, were investigated using SEM/EDX and quantitative XRD technique.
In this review article, the evolution mechanisms of metastable microstructure in a cold spray coating during deposition of spray particles were examined in terms of in-situ densification, residual stress, dislocation multiplication, grain refining, phase transformation and amorphization through typical materials.
In the current work, a novel hot-working process was applied to Nitinol rods with subsequent material hardness testing, electron backscatter diffraction (EBSD) and differential scanning calorimetry (DSC) analysis performed to determine the mechanical properties, grain texture and transformation temperatures of the processed Nitinol.
Three different types of austenite grains can be distinguished that have different transformation behaviors: austenite grains at the grain boundaries between ferrite grains, twinned austenite grains, and embedded austenite grains that are completely surrounded by a single ferrite grain.
The classical JMAK model is unable to describe the simulated grain-boundary nucleated transformation kinetics.
Decreasing grain size inhibits the transformation process and the temperature-induced transformation is completely suppressed for samples with average grain sizes of 7.5 nm and less.
