"To advance fabrication and use of amorphous metals, a fundamental and complete understanding of their size- and temperature-dependent deformation is required," the study's authors write. 2.1 Amorphous Alloy Fabrication and Characterization. The Zr 48 Cu 36 Al 9 Ag 7 (ZCAA) alloy ingots were prepared by vacuum arc melting with the mixture of stoichiometric elements of high purity (99.9%) of Zr, Cu, Ag and Al. The alloys were cast into the conventional arc-melting furnace. Repeated melting was carried out five times and the ingot was turned .
quenched material on a large scale. However, the demerit of this method is that the material has low density due to the porosity formed during the deposition of liquid droplets. The main difference in the present method of rapid quenching from the conventional melt-spraying method lies in the way of heat extraction from the melt-sprayed deposits. An effort was made to cool the surface . In this work, a novel approach is demonstrated to replicate amorphous metals from fused silica glass, derived from additive manufacturing and structured using hot embossing and casting, enabling .MGs, also known as amorphous metal alloys, arise from cooling a melt swiftly enough to bypass crystallization. Tracked back to the discovery of an amorphous phase in Au–Si alloys by Duwez et al., in 1960 [8]. MGs resist the organization of a crystalline structure due to the cooling speed, occupying a non-equilibrium, metastable state.
