摘要
A homogeneous melting state without any crystalline inclusions was achieved in an are melt furnace by using a ladle arc-melting-type furnace. Molten alloy for pouring can be melted completely by are 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.
