Effects of soaking time on the microstructure and mechanical properties of Nb-NbC/Fe core–shell rod-reinforced cast-iron-matrix composite fabricated through two-step in situ solid-phase diffusion

Journal of Materials Research and Technology, 2020
To overcome the disadvantages of low toughness of conventional particle reinforced steel/iron-based composites, a novel niobium-niobium carbide/iron (Nb-NbC/Fe) core–shell rod-reinforced cast-iron-matrix composites were fabricated through two-step in ...

Reliability analysis and micromechanics: A coupled approach for composite failure prediction [PDF]

, 2011
This work aims at associating two classical approaches for the design of composite materials: first, reliability methods that allow to account for the various uncertainties involved in the composite materials behaviour and lead to a rational estimation ...

Performance prediction of VO2-based smart radiation devices through semi-self-supervised learning with phase transition adaptation

Next Energy
Accurately forecasting the infrared radiation properties of multilayer systems exhibiting phase transition behavior presents a formidable challenge. In this study, we propose a physically-inspired Phase Transition Adaptation Model (PTAM) that leverages a
