A spheroidization-solidification competition parameter η is proposed to quantify morphology evolution, revealing that η ≤ 0.6 achieves >92 % spherical powders, while η ≥ 1 induces dendritic defects. P addition tunes η by elevating undercooling and viscosity, enabling precise morphology control. The research indicate that the addition of P enhances glass forming ability by reducing the liquidus temperature and stabilizing the deep eutectic composition, achieving a completely amorphous structure and suppressing the crystallization of α-Fe (Si, B). P-induced Fe-P-B covalent clustering reduces coercivity but slightly lowers saturation magnetization due to disrupted exchange coupling. Annealing optimizes magnetic properties via dual-phase evolution: low-P systems (x ≤ 2) exhibit α-Fe(Si,B) coarsening-driven Hc spikes, while high-P alloys form amorphous/nanocrystalline composites with exchange-spring effects. Cu/Nb synergistically stabilize nanograins and suppress coarsening. Spherical powder combined with LHP enables defect-free monolithic inductors, achieving a 4-fold higher DC breakdown voltage (>1000 V) and 23.8 % improved saturation current compared to cold-pressed counterparts.

The evolution of the shear behavior of the nodular pile-cemented soil interface was analyzed, and the effects of nodular pile node angle and width on the interface shear characteristics were investigated. The results indicate that the increase of the node angle not only reduces the interface bonding force, but also weakens the interlocking effect between the node and cemented soil. Increasing the node width within a certain range can significantly improve the interface shear resistance and deformation coordination by enhancing the mechanical interlocking effect and optimizing the stress transfer path. However, excessive increase of node width leads to intensified stress concentration within the cemented soil, resulting in a decrease in peak shear resistance. Finally, a nonlinear mechanical behavior model is proposed for the nodular pile-cemented soil interface.
