| Abstract Scope |
Casting of metallic glasses depends on various processing parameters that – beyond the glass-forming ability of the melt – determine the quality of cast parts. This is on one hand related to efficient undercooling upon solidification and competition with crystalline phases. On the other hand, optimized casting conditions allow to tune short- and medium-range order and modulate internal temperature gradients, thereby reducing the risk of cracking, thus strongly affecting the properties of cast parts. Exploring the correlations between melt overheating, the impact of mold temperature and the effect of interfacial reactions between melt and crucible on glass formation is crucial to optimize processing conditions for large-scale fabrication of metallic glasses as engineering materials. This talk will present recent results and examples for Zr-base glasses and will elucidate the correlations between parameters governing glass formation, aiming to derive guidelines for optimized processing through appropriate control of mold temperature and interfacial reactions.
