Abstract Mechanical properties of Al3BC are still not sufficiently investigated yet for its synthesis difficulties. In this work, the mechanical properties of single-crystal Al3BC were experimentally measured through nanoindentation and micropillar compression for the first time. The hardness, modulus and compression strength were measured to be 24 GPa, 332 GPa and 8.7 GPa, respectively. The high mechanical properties of Al3BC are one prerequisite for it as the reinforcement of Al alloys. This work is expected to have a profound significance for the design and optimization of Al3BC/Al composites.

纳米压痕和微柱压缩的 Al3BC 力学性能

摘要 由于合成困难，Al3BC 的机械性能仍未得到充分研究。在这项工作中，首次通过纳米压痕和微柱压缩实验测量了单晶 Al3BC 的机械性能。测得的硬度、模量和压缩强度分别为 24 GPa、332 GPa 和 8.7 GPa。Al3BC 的高机械性能是其作为铝合金增强体的先决条件之一。该工作有望对Al3BC/Al复合材料的设计和优化具有深远意义。
