Using a hybrid two-temperature model and molecular dynamics, we simulated ultrafast laser-metal interactions for gold thin films with varying crystallographic orientations and microstructure configurations. Microstructure features, namely grain size, grain topology, and local crystallographic orientation, controlled the rate and extent of lattice disorder evolution and phase transformation, particularly at lower applied fluences.

This alloy exhibits excellent corrosion resistance compared with other RHEAs.

A height distribution function derived from surface topology, a contact model representing asperity deformation, and a plowing model addressing the tribological effects of disc asperities form the core framework of the approach. The model primarily focuses on overall material behavior and micromechanical deformation within the brake system while maintaining computational efficiency, providing a mechanics-based, multi-scale representation suitable for large-scale simulations in consideration of pressure, temperature, and topological parameters. To ensure computational efficiency, the model is implemented through a structured approach optimized for finite element (FE) analysis, where it is transformed into an approximate function and embedded in FE subroutines. Its effectiveness is validated through FE simulations of reduced-scale brake dynamometer tests, which demonstrate its predictive capabilities and computational feasibility.
