We measured the bulk optical damage thresholds of pure and Nd-doped ceramic yttrium aluminum garnet (YAG), and of pure, Nd-doped, Cr-doped, and Yb-doped crystalline YAG. We used 9.9 ns, 1064 nm, single-longitudinal mode, TEM00 pulses, to determine that the breakdown thresholds are deterministic, with multiple-pulse thresholds ranging from 1.1 to 2.2 kJ/cm2.

A high-resolution and angle-insensitive structural color generation platform is demonstrated based on triple-layer aluminum-silica-aluminum metamaterials supporting surface plasmon resonances tunable across the entire visible spectrum. The color performances of the fabricated aluminum metamaterials can be strongly enhanced by coating a thin transparent polymer layer on top. The results show tha...

Grain-scale surface roughening due to plastic straining in polycrystalline aluminum is studied with the aid of a three-dimensional finite-element crystal-plasticity model. An improved understanding of the origin of surface roughening profiles in plastically strained aluminum is sought. Large-scale, Direct Numerical Simulation enables the computation of full-field solutions and the explicit cons...

In this study, aluminum (Al) film with high purity was coated on the Niobium (Nb) sheet by thermal evaporation under ultra-high vacuum. An Anodic Aluminum Oxide (AAO) nanotemplate prepared Nb sheet. During AAO preparation, three-dimensional (3D) nanopillars were grown We performed a simple 3D Artificial Intelligence (AI) analysis of nanopillars. According to experimental results, width is in ra...

In this paper, the energy absorption features of tri-layer explosive-welded deep-drawn cups subjected to quasi-static axial compressive loading are investigated numerically and experimentally. To produce the cups, tri-layer blanks composed of aluminum and stainless steel alloys were fabricated by an explosive-welding process and formed by a deep drawing setup. The quasi-static tests were carrie...

Two cold-rolled IF steel sheets sandwiching an aluminum sheet were heat-treated at 650°C, and the recrystallization behavior in interfacial region between pure was observed analyzed. The tongue-like structure of η-Fe2Al5 phase appeared reaction zone recrystallized characterized by equiaxed including subgrains surrounded η phase. In contrast, a bcc-ferrite elongated with pancake shape mainly oth...
