Changes in the crystallization sequence upon sulfur addition in the Zr52.5Cu17.9Ni14.6Al10Ti5 bulk metallic glass-forming liquid revealed by in situ high-energy x-ray diffraction

Bulk metallic glasses (BMGs) surpass the strength of steels and possess elasticity formability polymers. The key to obtain these properties is conserve amorphous structure a melt avoid crystallization during processing. In this work, change in sequence widely used BMG ${\mathrm{Zr}}_{52.5}{\mathrm{Cu}}_{17.9}{\mathrm{Ni}}_{14.6}{\mathrm{Al}}_{10}{\mathrm{Ti}}_{5}$ (Vit105) upon addition sulfur (${\mathrm{Zr}}_{51.45}{\mathrm{Cu}}_{17.54}{\mathrm{Ni}}_{14.31}{\mathrm{Al}}_{9.8}{\mathrm{Ti}}_{4.9}{\mathrm{S}}_{2}$; Vit105 ${\mathrm{S}}_{2}$) revealed by situ high-energy x-ray diffraction, both heating from glassy state cooling liquid electrostatic levitation. This methodology proves be powerful tool elucidate complete behavior complex BMG-forming liquids. experiments show that changes phases different manner than state. thermal stability at low temperatures increased, as supercooled region extended 60 77 K glass transition temperature increases 671 692 K. However, decreased cooling, causing reduced glass-forming ability.
