Effect of interfacial thermal mismatch on mechanical properties of metal matrix composites

open access: yesFenmo yejin jishu, 2023
The interfacial thermal mismatch stress will generate at the reinforcement/metal matrix heterogeneous interfaces during the cooling process of the metal matrix composites (MMCs), due to the large mismatch of the coefficient of thermal expansion (CTE ...

Superflexible and Lead-Free Piezoelectric Nanogenerator as a Highly Sensitive Self-Powered Sensor for Human Motion Monitoring

open access: yesNano-Micro Letters, 2021
For traditional piezoelectric sensors based on poled ceramics, a low curie temperature (T c) is a fatal flaw due to the depolarization phenomenon. However, in this study, we find the low T c would be a benefit for flexible piezoelectric sensors because ...

Metal-matrix composite materials: Manufacturing and joining methods

open access: yes, 2022
Composite materials are solid materials produced by combining two or more components to provide the required properties. Metal-matrix composites (MMCs) are composite materials that have at least two component materials, one of which is metal (Al, Mg ...

Metal Matrix Composites

open access: yesEncyclopedia
Metal matrix composites (MMCs) are engineered multiphase materials in which a continuous metallic matrix contains deliberately introduced reinforcing phases. Their properties arise from the combined effects of the matrix, reinforcement, interface, processing route and spatial architecture.
