Symposium SF01-Bulk Metallic Glasses

The ability to create bulk metallic alloys lacking long-range order and grain boundaries has attracted significant attention in both the academic and commercial communities. These materials, called bulk metallic glasses (BMGs) They exhibit unique properties, including near theoretical strength, high elastic strain limit and wear resistance along with excellent soft-magnetic and catalytic properties. Modern BMGs can also show processing advantages, and additive manufacturing recently has enabled large scale components to be produced. They have established themselves as a viable class of engineering materials with exciting opportunities in fundamental science and broad potential commercial applications. The continuation of rapid growth in the field of BMGs can be attributed to advancements in our fundamental understanding of their structure and deformation, improved understanding of the liquid structural state, the development of BMG forming alloys based on elements essentially covering all transition metals, and new processing methods such as thermo-plastic forming and additive manufacturing. The unique vitrification behavior of BMGs allows them to be processed similar to both plastics and metals. Various plastic processing and fabrication techniques have been adapted and tailored to the specific characteristics of BMGs. The sluggish crystallization kinetic, coupled with the absence of an intrinsic feature size limitation enables one to use BMGs over a wide range of length scales. Novel insights into processing has also been explored for improving and tailoring properties of BMGs. From a fundamental point of view, recent research progress has involved micromechanistic models for processing-structure-property relationships of BMGs, which has been a significant challenge due to the lack of long-range order, grains and their boundaries, and other typical structural features observed in metals.
