Abstract

A homogeneous melting state without any crystalline inclusions was achieved in an arc melt furnace by using a ladle arc-melting-type furnace. Molten alloy for pouring can be melted completely by arc heating just above the mold in a pseudo float melting (PFM) state. We combined a ladle arc-melt-type furnace and the squeeze cast method to produce bulk amorphous alloy sheet with a single amorphous phase structure, thereby successfully producing crystalline inclusion-free Zr₅₀Cu₃₀Ni₁₀Al₁₀ bulk amorphous alloy sheets. The tensile strengths of the Zr₅₀Cu₃₀Ni₁₀Al₁₀ bulk amorphous alloys exceeded 1800 MPa, and the bending deflection of the alloys was improved by a factor of 10 using the PFM process.
