Abstract

The master alloy ingots (MAI) with the nominal composition Zr_52.5Ti₅Cu_17.9Ni_14.6Al₁₀ and Fe₆₁Co₇Zr₁₀Mo₅W₂B₁₅ (at%) were prepared by arc-melting in Ti-guttered Ar atmosphere. The Zr-based buttons of 6 mm and 9 mm in diameter were fully amorphous, but those of 13 mm in diameter experienced crystallization. The glass forming ability (GFA) of Fe-based alloys was relatively lower, and the buttons obtained were fully crystallized. The microhardness of the Zr-based buttons was about 500 (Hv), and the Fe-based rod obtained by injection technique exhibited a high Vickers hardness of 1329. In addition, an amorphous-crystalline transition layers were observed in both the buttons and the rods.
