Abstract Tremendous properties of bulk metallic glasses (BMGs) have led to numerous potential applications in the past few years. An obvious interest has been given to their potential as structural material given their high mechanical properties and their ability to be produced in bulk parts of several millimeters in size. Unlike their crystalline counterparts, they also show very promising insulating properties due to the absence of a periodic lattice. In the present work, the interest of using bulk amorphous metallic alloys as materials combining good structural properties and thermal insulation is discussed. The study of Hf-rich BMGs enables to reduce the thermal losses through a higher σc/κ performance ratio and thus shows very good potential for future insulating and structural applications.

富含 Hf 的块状金属玻璃作为潜在的绝缘结构材料

摘要 在过去几年中，块状金属玻璃 (BMGs) 的巨大特性导致了许多潜在的应用。考虑到它们的高机械性能和可批量生产几毫米尺寸的能力，人们对它们作为结构材料的潜力给予了明显的兴趣。与晶体对应物不同，由于没有周期性晶格，它们还显示出非常有前途的绝缘性能。在目前的工作中，讨论了使用块状非晶金属合金作为结合良好结构性能和绝热性的材料的兴趣。对富含 Hf 的 BMG 的研究能够通过更高的 σc/κ 性能比来减少热损失，因此在未来的绝缘和结构应用中显示出非常好的潜力。
