Composite quadrupole order in ferroic and multiferroic materials [PDF]

open access: yesJournal of Physics: Condensed Matter, 37, 05LT01, 2025, 2023
The formalism of composite and intertwined orders has been remarkably successful in discussing the complex phase diagrams of strongly correlated materials and high-$T_c$ superconductors. Here, we propose that composite orders are also realized in ferroelectric and ferromagnetic materials when lattice anisotropy is taken into account.

Uncertainty Quantification and Composition Optimization for Alloy Additive Manufacturing Through a CALPHAD-based ICME Framework [PDF]

open access: yesnpj Computational Materials, 6 (2020) 188, 2020
During powder production, the pre-alloyed powder composition often deviates from the target composition leading to undesirable properties of additive manufacturing (AM) components. Therefore, we developed a method to perform high-throughput calculation and uncertainty quantification by using a CALPHAD-based ICME framework (CALPHAD: calculations of ...

IMAGE ON COMPOSITE MATERIALS

open access: yesJournal of Research and Innovation for Sustainable Society, 2020
Composite materials are materials with remarkable properties, obtained by combining two or more homogeneous macroscopic materials, with different structure and properties, which, by combining the individual qualities of the components, form a heterogeneous material with improved overall performance.

Drilling Damage in Composite Material [PDF]

open access: yesMaterials, 2014
The characteristics of carbon fibre reinforced laminates have widened their use from aerospace to domestic appliances, and new possibilities for their usage emerge almost daily. In many of the possible applications, the laminates need to be drilled for assembly purposes.

Performance comparison of 2-1-3, 1-3 and 1-3-2 piezoelectric composite transducers by finite element method [PDF]

open access: yesCondens. Matter Phys., 2018, vol. 21, No. 1, 13702, 2018
1-3 type, 1-3-2 type and 2-1-3 type piezoelectric composites are three proper smart materials for the design and manufacture of ultrasonic transducers. They have been proposed in different stages but possess similar properties. Compared with the initial 1-3 type composite, 1-3-2 composite is of higher mechanical stability. Compared with 1-3-2 composite,
