Abstract

We report an intriguing anisotropic deformation behavior of lithium disilicate crystal under tensile loadings via molecular dynamics simulations. The crystal undergoes clear brittle cleavage in the [010] direction, while exhibiting a first-order transition with the critical stress of around 8 GPa in the [100] direction. The transition is exclusively facilitated by local Li-O bond breakage spreading to the whole sample. This hierarchical deformation mechanism enables overall structure integrity while undergoing large degrees of deformation. To the best of our knowledge, this is the first observation on this intriguing deformation behavior that might inspire new designs of tougher lithium disilicate glass-ceramics.
二硅酸锂晶体有趣的变形转变行为
我们报告了一个有趣的各向异性变形行为的二硅酸锂晶体在拉伸载荷下通过分子动力学模拟。晶体在[010]方向发生了明显的脆性解理,而在[100]方向发生了一级转变,临界应力约为8 GPa。这种转变完全是由局部Li-O键断裂扩展到整个样品所促进的。这种分层变形机制使整体结构在经历大程度变形的同时保持完整性。据我们所知,这是对这种有趣的变形行为的首次观察,可能会激发更坚韧的二硅酸锂玻璃陶瓷的新设计。
