Influence of Cooling Rates and Titanium Content on Hot Ductility in Niobium‐Fixed Microalloyed Steels

steel research international, Volume 97, Issue 2, Page 719-730, February 2026.
The hot ductility of four microalloyed steels was examined under varying cooling rates and titanium contents. Hot tensile testing and microscopic analysis revealed that ferrite formation and TiNb(CN) precipitation critically influence hot ductility. Lower cooling rates enhance ductility by increasing ferrite thickness and modifying precipitate features,

A machine learning approach to finite element modeling of sintering deformation using densification data

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract This paper presents a recent development in the densification‐based finite element method (DFEM) of sintering deformation, in which a machine learning model replaces the volumetric component of classical constitutive laws. Accurate constitutive laws are traditionally considered essential for finite element (FE) modeling; however, this study ...

Effect of Heat Treatment on Pore Architecture and Associated Property Charges in Plasma Sprayed TBCs

, 2007
Plasma sprayed TBCs exhibit many interlamellar pores, voids and microcracks. These microstructural features are primarily responsible for the low global stiffnesses and the low thermal conductivities commonly exhibited by such coatings.

Anomalously large oxygen-ordering contribution to the thermal expansion of untwinned YBa2Cu3O6.95 single crystals: a glass-like transition near room temperature

, 2000
We present high-resolution capacitance dilatometry studies from 5 - 500 K of untwinned YBa2Cu3Ox (Y123) single crystals for x ~ 6.95 and x = 7.0. Large contributions to the thermal expansivities due to O-ordering are found for x ~ 6.95, which disappear ...

Phonon density of states and heat capacity of La_(3−x)Te_4 [PDF]

, 2009
The phonon density of states (DOS) of La_(3−x)Te_4 compounds (x=0.0,0.18,0.32) was measured at 300, 520, and 780 K, using inelastic neutron scattering.

Laser-dilatometer calibration using a single-crystal silicon sample

International Journal of Optomechatronics, 2019
Marginal changes in geometrical dimensions due to temperature changes affect the performance of optical instruments. Highly dimensionally stable materials can minimize these effects since they offer low coefficients of thermal expansion (CTE).
