Composition of ω-Phase Particles in Ti(Mo) Alloys Studied by Anomalous X-ray Diffraction

Crystals, 2019
Nanoparticles of hexagonal ω phase in bcc-Ti(Mo) single crystals ( β phase) occur due to a diffusionless athermal β to ω transformation and they grow during follow-up ageing at elevated temperatures, while the ...

Effect of Ultra-Fast Heat Treatment on the Subsequent Formation of Mixed Martensitic/Bainitic Microstructure with Carbides in a CrMo Medium Carbon Steel

Metals, 2019
The current work focuses on complex multiphase microstructures gained in CrMo medium carbon steel after ultra-fast heat treatment, consisting of heating with heating rate of 300 °C/s, 2 s soaking at peak temperature and subsequent quenching. In order

Thermo-mechanical-coupling-induced structural transformation and strain-hardening in Ti-V-Zr-Nb-Al multi-component alloys

Materials Research Letters
High-temperature strain softening limits the application of lightweight refractory multi-component alloys (LRMCAs) in aerospace and nuclear engineering. This study reports an anomalous strain-hardening behavior in a non-equiatomic Ti60(V2Zr3Nb2)34Al6 (A6)

Extension of Isoconversional Analysis to Diffusion‐Controlled Epoxy Cure Kinetics: Comparison With Model‐Fitting Approaches

Polymer Engineering &Science, EarlyView.
Extending isoconversional analysis of DSC data to diffusion‐controlled regimes captures the rise in apparent activation energy upon vitrification and yields TTT diagrams of RTM6 epoxy resin that remain accurate when diffusion, rather than chemistry, governs the cure rate.
