Web16 de mai. de 2024 · Alkali aluminoborate glasses have recently been shown to exhibit a high threshold for indentation cracking compared to other bulk oxide glasses. However, to enable the use of these materials in engineering applications, there is a need to improve their hardness by tuning the chemical composition. In this study, we substitute alkaline … Web15 de jan. de 2024 · However, for the Ta 46.5 W 35 Co 18.5 thin film with amorphous structure, multiple partial circular patterned SBs are found in the pile-up zone around the edges of the indent, indicating that the pronounced plastic deformation occurred during the nanoindentation process, which is different from the other high-hardness metallic glass … Web28 de set. de 2015 · Or conversely, the material could exhibit high hardness but not be strong and tough, meaning that an impact would not abrade the surface but the material could still fracture internally. In contrast to other materials, glasses are typically strong, hard, and tough, which leads to high impact resistance. c# is empty string null
