Hydrogenation treatment under several gigapascals assists diffusionless transformation in a face-centered cubic steel [PDF]
Scientific Reports, 2021 The use of hydrogen in iron and steel has the potential to improve mechanical properties via altering the phase stability and dislocation behavior. When hydrogen is introduced under several gigapascals, a stoichiometric composition of hydrogen can be ...

Diffusionless transformation of soft cubic superstructure from amorphous to simple cubic and body-centered cubic phases [PDF]
Nature Communications, 2021 The arrangements of defect lines in liquid crystal blue phases provide promising templates for photonic crystals. Here Liu et al. investigate in detail how inter-phase transitions proceed, by intercepting nucleation with on-demand cross linking of a ...

Evolution of the microstructure of cobalt during diffusionless transformation cycles [PDF]
Journal of Materials Research, 1990 Differential scanning calorimetry and transmission electron microscopy have been used to study thermal fatigue due to diffusionless phase transformation cycling in pure cobalt. Thermal cycling through the allotropic (hcp ↔ fcc) transformation results in a temperature shift of the calorimetric peaks, which means a delay of the transformation.

Driving diffusionless transformations in colloidal crystals using DNA handshaking [PDF]
Nature Communications, 2012 Many crystals, such as those of metals, can transform from one symmetry into another having lower free energy via a diffusionless transformation. Here we create binary colloidal crystals consisting of polymer microspheres, pulled together by DNA bridges, that induce specific, reversible attractions between two species of microspheres.

INTERNAL FRICTION PHENOMENA ASSOCIATED WITH DIFFUSIONLESS PHASE TRANSFORMATIONS IN ALLOYS
Le Journal de Physique Colloques, 1981 Internal friction and ultrasonic attenuation peaks associated with diffusionless phase transformations in alloys, such as thermoelastic martensites and others, were reviewed. They were discussed from the stand point of (1) Understanding the mechanism of the phase transformations and (2) Developing new alloy materials of high damping capacity for ...
