Damage micromechanisms in alumina hybrid bilayers with graded interfaces

梯度界面氧化铝杂化双层膜损伤的微观机制。本项目为具有梯度界面的高性能氧化铝杂化材料提出了一种新的设计理念。这一工艺的关键是在外层均匀氧化铝层和内部异质氧化铝杂化层之间加入薄梯度界面，前者用于强度、硬度和耐磨性，后者用于损伤容限。该项目将探索有关分级界面对失效微观机制的影响的悬而未决的问题。这一领域的进展将为设计新的下一代层状材料提供新的策略或见解。

Damage micromechanisms in alumina hybrid bilayers with graded interfaces. This project proposes a new design concept for high performance alumina hybrids with graded interfaces. The key to this process is the incorporation of thin graded interfaces between an outer homogeneous alumina layer for strength, hardness and wear resistance, and an inner heterogeneous alumina hybrid layer for damage tolerance. The project will explore unresolved issues concerning the effect of graded interfaces on the failure micromechanisms. Advances in this area will provide new strategy or insights for designing novel next generation layered materials.
