Samenvatting

A paramount challenge in materials science is to design glasses that exhibit not only high strength but also toughness, i.e., the ability to resist brittle failure. This property combination constituting damage tolerance appears to be self-excluding; tough materials need to dissipate energy, for example, by plasticity, whereas high-strength materials are designed to prevent irreversible energy dissipation, thus plastic deformation. Hence, materials exhibiting concomitant high toughness (where bond breakage occurs) and high strength (where bond breakage should not occur) are chimeric from the perspective of chemical bonding, imposing severe challenges on the design of these materials. Even though there are damage-tolerant glasses reported in literature, which are predominantly developed applying empirical alloying guidelines, the underlying physical and chemical mechanisms are not understood on the atomic scale. Hence, this work focuses on identifying the origin of damage-tolerant glasses.
