Research ArticleOpen accessIn the keywordsAbout Glassy Amorphous Metal InjectionRaffaella Aversa, Relly Victoria Petrescu, Antonio Apicella et al.The paper aims to present studies on the melt flow, melting and rheology of melting in a super-cooled metastable liquid metal, which is injection molded, of the Zr44-Ti11-Cu10-Ni10-Be25 alloy, which can induce selective crystallization. In this process, high Be-velocities were observed, Cu and Ni atoms that crystallized differently in superficial bulk metallic bulk liquids. It wants to highlight and analyze … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 22 Jan 2018 · 7,438 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsGlassy Amorphous Metal Injection Molded Induced Morphological DefectsRaffaella Aversa, Daniela Parcesepe, Relly Victoria V. Petrescu et al.Melt rheology in injection molded metastable supercooled liquid metal of Zr44-Ti11-Cu10-Ni10-Be25 alloy may induce selective crystallizations. High mobility Be, Cu and Ni atoms have been observed to differently crystallize in bulk metal glassy supercooled liquids. Here, we analyze the result of morphological microscopic observation conduct on Bulk Metallic Glass (BMG) with composition of a commercial liquid metal alloy (LM001B). The … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 27 Dec 2016 · 8,938 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsProcessability of Bulk Metallic GlassesRaffaella Aversa, Daniela Parcesepe, Relly Victoria V. Petrescu et al.Microfluidic Shear Flow Instabilities in Injection Molded Glassy Metal are investigated. The formation of microfluidic shear flows instabilities involving the presence of different viscosities fluids has been observed in injection molded Bulk Metallic Glasses. The complex rheology of injection molded metastable glassy metal, which has been hypothesized to induce selective clustering of atoms of different steric hindrance, is discussed. Smaller … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 15 Feb 2017 · 7,487 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsFactors Affecting Chemo-physical and Rheological Behaviour of Zr44-Ti11-Cu10-Ni10-Be25 Metal Glassy Alloy Supercooled LiquidsApicella Antonio, Aversa RaffaellaSegregation by selective cold crystallizations and glass transition changes in Zr44-Ti11-Cu10-Ni10-Be25 metal supercooled metastable liquid annealed at different temperatures have been theoretically correlated to melt viscosity modifications. Crystallization behavior has been found to be principally related to the high mobility and smaller Be, Cu and Ni atoms. Multiple exothermal peaks in isothermal DSC annealing’s have been observed in these bulk … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 25 Feb 2016 · 8,142 accessesView PDF Cite
