Damage micromechanisms in alumina hybrid bilayers with graded interfaces

具有梯度界面的氧化铝杂化双层损伤微机制。本课题提出了一种具有梯度界面的高性能氧化铝杂化材料的新设计理念。该工艺的关键是在具有强度、硬度和耐磨性的外均质氧化铝层和具有损伤容忍度的内非均质氧化铝杂化层之间结合薄梯度界面。该项目将探索有关梯度界面对破坏微观机制影响的未解决问题。这一领域的进展将为设计新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.
