Finite-Element Analysis of Oscillations in Damaged Pipeline Sections Reinforced With a Composite Material by Arman Moldagaliyev, Nurlan Zhangabay, Marco Bonopera, Talzhan Raimberdiyev, Shairbek Yeshimbetov, Seraliyev Galymzhan, Yermek Anarbayev

“…The outcome showed that to compensate for the stress concentration in the damaged zone of a pipeline with a thickness between 11.9 and 14.3 mm, the thickness of the composite wrap should be 2÷4 mm, that is, not lower than 17% of the original pipeline thickness at thinning and not lower than 34% of the original pipeline thickness at large cracks. An increment in the pipeline thickness from 11.9 up to 14.3 mm with a reinforced composite lining leads to an increment in the first oscillation frequency not higher than 0.1%. …”

Thermally Induced Phenomena in Amorphous Nifedipine: The Correlation Between the Structural Relaxation and Crystal Growth Kinetics by Roman Svoboda

“…The enthalpy relaxation was described in terms of the Tool–Narayanaswamy–Moynihan model, with the relaxation motions exhibiting the activation energy of 279 kJ·mol⁻¹ for the temperature shift, but with a significantly higher value of ~500 kJ·mol⁻¹ being obtained for the rapid transition from the glassy to the undercooled liquid state (the latter is in agreement with the activation energy of the viscous flow). …”

Intergranular creep resistance affected by grain boundary carbides to suppress lamellae γʹ precipitation in a specially designed inconel 740H variant by Cheol-Hyeok Yang, Chiwon Kim, Siyeon Kim, Hi-Won Jeong, Hyungsoo Lee, Dae Won Yun, Hyun-Uk Hong

“…During creep, both samples showed Orowan bypassing dislocations around γʹ particles, but only the STBG sample exhibited coarse, nodule-like γʹ precipitation at carbide-free grain boundaries, leading to easier intergranular cracking. The higher fraction of grain boundary carbides in the SAG sample effectively suppressed nodule-like γʹ formation and reduced creep damage by strengthening the grain boundaries, preventing dislocation impingement. …”
