Production of Zirconium based Amorphous Alloy by Mechanical Alloying and Sintering Al-based Composite with Amorphous Particles, M.Sc. Thesis Sharif University of Technology ; Pourazarang, Kazem (Supervisor) ; Abachi, Parvin (Supervisor)
Abstract
Production of copper-zirconium amorphous alloys by mechanical alloying and the process of changing crystal structure to amorphous, was examined. The amount of progress of amorphization has been checked by x-ray analysis after different hours of milling. By increasing the percentage of zirconium in this type of alloy, the process of amorphization has been improved. But There is a limiting factor which is due to the tendency of zirconium to produce oxide and nitride phase. Also, the effect of excessive elements on crystal structure changing has been checked. Hence, adding elements like nickel or aluminum has a different effect on the process of amorphization. adding aluminum to the system...
