High-temperature Mo-based bulk metallic glasses

Among bulk metallic glass (BMG) alloys, molybdenum(Mo)-based BMGs are lacking due to the weak glass forming ability (GFA) of existing Mo-based alloys. In this work, we developed a novel family of low-cost refractory Mo-Co-B BMGs with enhanced GFA and high thermal stability. These Mo-based BMGs exhibit ultra-high glass transition temperatures ranging from 1020 to 1048 K, paired with exceptional nano-hardness and Young's modulus up to 17.1 GPa and...
