Shock wave attenuation in a high-entropy alloy with pre-existing dislocation network by Hongcai Xie, Guoxiang Shen, Zhichao Ma, Wei Zhang, Hongwei Zhao, Luquan Ren

“…However, the in-depth understanding of dynamic deformation mechanisms remains limited due to technological constraints in real-time detection of microstructural evolution at the atomic level. In present work, non-equilibrium molecular dynamics (NEMD) simulations were performed to study the shock response of FeCoNiCrCu HEAs with pre-existing dislocation network. …”

Macroscopic perspective on phase transition behavior of natural single-crystal graphite under different pressure environments by Xiaoshuang Yin, Songyang Li, Lijuan Wang, Peiyuan Liu, Zhihai Cheng, Huiyang Gou, Liuxiang Yang

“…Here, we report on the pressure-induced phase transition behavior of natural single-crystal graphite under three distinct pressure-transmitting media from a macroscopic perspective using in situ two-dimensional Raman spectroscopy, scanning electron microscopy, and atomic force microscopy. The surface evolution process of graphite before and after the phase transition is captured, revealing that pressure-induced surface textures can impede the continuity of the phase transition process across the entire single crystal. …”

A theoretical prediction for generating isolated attosecond pulse in water window utilizing instantaneous frequency change of two-color driving laser pulse by Masoumeh Dehghanian, Mohammad Sabaeian, Siamak Noorizadeh

“…Abstract This work reports on the theoretical generation of isolated soft-X ray 106 attosecond pulse within the water window spectral region, through interacting a chirped two-color femtosecond laser pulse with a hydrogen atom. To construct this pulse, a chirped 3.5 optical cycle (9.33 fs) laser pulse with a wavelength of 800 nm and an intensity of $$5\times {10}^{14}\frac{\text{W}}{{\text{cm}}^{2}}$$ is used as the main field. …”

Matematical modeling of the process of enlarging the austenitic grain during high-temperature heating of alloy structural steel by V. A. Kukareko, B. M. Gatsuro, A. N. Grigorchik, A. N. Chichin

“…A phenomenological model describing the mechanism of formation and growth of austenitic grains in steels under heating at different speeds is developed.It is concluded that the slow heating of steels in the interval of phase a®g transformation contributes to the formation of a complex of small austenite grains separated by high angle boundaries with adsorbed on them by impurity atoms, which ensures higher resistance grain structure to coalescence and reduce the rate of migration of the boundaries during prolonged hightemperature austenization.…”
