Special Issue Information

Dear Colleagues,

Cryogenic treatment has become an important process in recent years, helping to tailor the microstructure and modify the final properties of materials; this includes the corrosion resistance, tribocorrosion resistance, wear resistance, fatigue resistance and surface properties. Cryogenic treatment is a treatment that affects both the surface and the bulk of the material at the same time, which is an advantage over other conventional treatments. By changing the microstructure and final properties of materials, cryogenic treatment can not only extend their life, but also the final component or tool, resulting in lower maintenance and processing costs. The application of cryogenic treatment can be found in medicine and implants, in the music industry for enhancing the sound of stringed and brass instruments, and in the automotive industry, oil and gas industry, mining industry, tool industry, electronics, robotics and many other conventional and emerging technologies. Cryogenic treatment can be applied to a wide variety of materials, from metallic (ferrous and non-ferrous alloys) to non-metallic, and to polymers, ceramics and composites.

This Special Issue is dedicated to the cryogenic treatment of various materials, with an emphasis on the corrosion properties, degradation (hydrogen test properties, tribocorrosion, tribology) and surface properties of materials.

All types of contributions are welcome (reviews, original articles, etc.).

This study investigates the degradation of mechanical properties in CuZr metallic glasses (MGs) under cyclic loading using molecular dynamics simulations. Both as-cast (AC) and cryogenically thermal-cycled (TC) samples with Cu36Zr64 and Cu64Zr36 compositions were analyzed. Results show that cyclic loading significantly degrades Young’s modulus, ultimate tensile stress, and toughness, with most pronounced reductions occurring in the initial cycles. TC samples exhibit improved ductility and stability compared to AC samples. In contrast, AC samples demonstrate greater initial strength but faster degradation. Cu-rich samples maintain higher strength but degrade similarly to Cu-poor samples. The AC Cu-rich sample experiences more localized deformation and delayed degradation, while TC and AC Cu-poor samples quickly reach a steady state. These findings highlight the influence of atomic composition and thermal treatments on the mechanical performance and degradation behavior of MGs. Full article
