|Abstract:||Glass-forming ability (GFA) in relation to microstructure evolution in the ternary Fe-Nb-B and Fe-Zr-B and quaternary Fe-(Nb,Zr)-B systems was systematically studied in a three-dimensional composition space. Through navigating, it was revealed that alloys with the optimum glass-forming ability (GFA) are coupled with composition regions surrounded by competing crystalline phases. Alloys Fe71Nb6 B23, Fe77Zr4B19 and Fe71(Nb0.8Zr0.2)6 B23 were illustrated to be the best glass formers in the ternary Fe-Nb-B and Fe-Zr-B systems and the quartenary Fe-(Nb,Zr)-B system, respectively, with a critical size for amorphous formation up to 2 mm. They were compared with the theoretical predictions on the basis of an efficient dense-packing model, and good agreements were obtained. © 2008 Materials Research Society.|
