Achieving excellent comprehensive thermal performances in (GF+CF)/(Cu+Ti) composites via hybrid reinforcement strategy and highly oriented structure

Journal of Materials Research and Technology
Although graphite flakes (GF)/Cu composites have high thermal conductivity (TC) in the basal plane direction of GF, the problem of high coefficient of thermal expansion (CTE) makes it unable to meet the requirements of thermal management.

Effect of Cu and CuP Additions on the Microstructure and Nanoindentation‐Based Fracture Behavior of CoNiAlSi Ferromagnetic Shape Memory Alloys

Advanced Engineering Materials, EarlyView.
Cu and combined Cu–P microalloying refine the microstructure and enhance the nanoindentation‐derived fracture resistance of CoNiAlSi ferromagnetic shape memory alloys without suppressing the martensitic transformation. Comparative SEM, DSC, and nanoindentation results reveal that the CuP‐containing alloy provides the most balanced response, achieving ...

Study of the Coefficient of Thermal Expansion for Steel Q235

, 2011
The dynamic coefficient of thermal expansion for steel Q235 during cooling was investigated using experimental measurements and model calculations. The coefficient of thermal expansion under 1400°С was measured with a thermal dilatometer. The coefficient

Temperature dependence of the thermal-expansion coefficient of vacancies

Physical Review B, 1980
Self-diffusion experiments on Zn and Cd under pressure show that the thermal-expansion coefficient ${\ensuremath{\beta}}^{\mathrm{act}}$ of the activation volume decreases with temperature according to the law $\frac{1}{T}$. On the other hand in the case of Na recent calculations show that ${\ensuremath{\beta}}^{\mathrm{act}}$ increases with ...

A Multi‐Scale Machine Learning Framework for the Inverse Design of High Entropy Alloys

Advanced Engineering Materials, EarlyView.
High‐entropy alloys offer vast potential for various applications, including electrocatalysis; however, their compositional complexity challenges conventional screening. We introduce an inverse‐design framework combining two neural networks to determine optimal compositions and reconstruct nanoparticle geometry from targeted properties and conventional

Demo 14-14 Negative Expansion Coefficient of Water

, 2001
A Pyrex beaker, which has a coefficient of thermal expansion much less than that of water, is completely filled with water at 0?C, with a column of water extending into a glass tube connected to the top of the beaker, as in Figure 1.
