The magnetic cooling utilizing magneto-caloric effect is recognized as promising energy efficiency and environmentally friendly technology. Here we report a systematical study on the microstructures, properties cryogenic performances of Gd 20 Ho Tm Cu Ni amorphous ribbons. It found that ribbons reveal second-order phase transition are accompanied by table-shaped effect. calculated magnetic-entropy-change maximum |Δ S M |, temperature averaged entropy change (i.e., TEC(10)), refrigerant...
The aluminum alloy components on automobile often experience high strain rate deformation during accidents. dynamic behavior and constitutive model are crucial for analysis of vehicle body collisions failures. In this work, the 7A75 plate was heat treated according to standard manufacturing procedures. Quasi-static tensile experiments were conducted aged in a wide range from 0.001 s-1 500 s-1. revealed, models established. It found that has strong sensitivity, its mechanical properties can...
Rare-earth based amorphous alloys with promising glass forming ability (GFA) and considerable magnetocaloric effect (MCE) are extensively exploited for magnetic refrigeration (MR) materials. Here, the GFA, properties, MCE, performance of RE60Al20Ni20 (RE = Tm, Er, Ho) ribbons were investigated. A phase transition (paramagnetic to ferromagnetic, second-order) ignorable field thermal hysteresis was found around TC ∼ 4.4 K Tm60Al20Ni20, ∼9.5 Er60Al20Ni20, ∼17.9 Ho60Al20Ni20. For a change ΔH 50...
We study the coupling of mode in time for non-Hermitian cavities. Using variational principle, we provide a self-consistent approach to hybridization cavities from first-principle Maxwell's equations. first extend reaction concept reversal adjoint system using scalar inner product. apply our theory parity-time symmetric cavities, and obtain excellent agreement with results obtained by finite element fullwave simulations. In contrast, conventional coupled complex product fails capture...
Mode properties of circularly symmetric waveguides with one special type bianisotropy are studied using finite element approach. We find that the polarization degeneracy in can be eliminated, by introducing intrinsic crossing coupling between electric and magnetic moments constituent units waveguide media. Breaking high order mode groups is also confirmed numerically. With bianisotropic parameters chosen this work, x y-polarized modes remain decoupled. Typically, completely unchanged, while...
Abstract A specialized lifting tool for aero-engine in a workshop broke down after two months of use, resulting damage to the workpiece and significant economic losses. The incident also posed serious production hazard workshop. In this study, series characterization methods including macroscopic trace observation, fracture analysis, physical chemical testing, microstructure hardness testing were conducted analyze cause fracture. Based on simulation methods, reliability design was evaluated....
